#115 Hercules NGC Project Part 9: Uranometria Charts 50, 49

Uranometria Chart #50

Note that the right hand side of the chart is dealt with on the Chart 51 page.

oc DoDz 6:  3'.5; 5 *s; Br. * mag.8.8:  Observed at 60x and 100x.  It is a 5-star asterism, and non too exciting.

eg 6255:  3'.6 x 1'.5:  Vis. 12.7; SB 14.4:  Far from being a showpiece object (and far from being visual mag. 12.7), this one is fun to locate anyway.  It seems closer to mag. 14, it's large size likely makes it too faint for smaller apertures.  In the 12" it was seen at 100x.  It is very large, very oval, and very faint.  At 136x the center is brighter, and it is even larger overall.  At 187x it is fading, but a few stars involved can now be seen.
http://www.ngcicproject.org/dss/n/6/n6255.jpg

eg 6257:  0'.8 x 0'.3:  Vis. 15.1; SB 13.4:  These really faint galaxies can wear you down if they are not spaced out with brighter objects.  This was my 2nd one of the night, after only 3 objects viewed.  Luckily, a pinpoint hand-drawn map got me right to the scene, with a northwest/southeast line of 4 stars pinpointing the location.  Glimpsed at times with averted vision at 250x and 272x.  It is very faint and elongated.
 http://www.ngcicproject.org/dss/n/6/n6257.jpg

eg 6274:  0'.6; 0'.5:   Vis. 13.8; SB 12.3:  Using a detailed, hand-drawn map, the main galaxy was
eg 6274A:  0'.7 x 0'.2:  Vis./SB ??:   spotted at 136x.  It was round and not difficult to see.  Views were decent at 187x.  At 272x, 74A was glimpsed as a tiny add-on, non-stellar, with averted vision.  It seemed an extension to the south following end of the main galaxy.  I never would have noted this unless I knew exactly what I was looking for beforehand.
 http://www.ngcicproject.org/dss/n/6/n6274.jpg

eg 6282:  0'.7 x 0'.5:  Vis. 14.4; SB 13.1:  Located south following eg 6274, I used the same detailed chart as above (I use dso-browser).  136x actually gave a pretty good view.  The galaxy is oval, faint, but distinct.  A very faint star is  following.
 http://www.ngcicproject.org/dss/n/6/n6282.jpg

eg 6330:  1'.4 x 0'.5:  Vis. 14; SB 13.5:  Viewed at 136x and 187x, the galaxy is small, faint, and very oval.  I managed a sketch, though.
 http://www.ngcicproject.org/dss/n/6/n6330.jpg

eg 6349:  0'.8 x 0'.2:  Vis. 14.3; SB 12.2:  After some searching I located 49 at 136x.  At 187x both
eg 6351:  0'.2 x 0'.2:  Vis. 15.2; SB 13.5:  galaxies can be seen!  At 200x and 250x a very small, faint slash can be seen, with the smaller haze just following, mingled with a faint star or two.
 http://www.ngcicproject.org/dss/n/6/n6349.jpg

_____________________________________________________________________________

eg 6364:  1'.5 x 1'.2:  Vis. 12.9; SB13.4:  Viewed at 136x, 187x, and 250x.  The galaxy has a bright, stellar core.  The envelope of haze surrounding it is small and quite faint.  There is a nearby faint star, north.
http://www.ngcicproject.org/dss/n/6/n6364.jpg

eg 6367:  0'.8 x 0'.7:  Vis. 14.2; SB 13.5:  Conveniently located near a mag. 8 star, it was glimpsed at 100x and showing a stellar core.  Transparency was improving!  It was small but pretty bright at 136x.  187x shows a small, round, and pretty bright galaxy.  250x with averted vision shows it larger now, but fading a bit.
 http://www.ngcicproject.org/dss/n/6/n6367.jpg

eg 6433:  2' x 0'.5:  Vis. 13.3; SB 13.1:  Another good guess showed this one as a long slash, and pretty faint.  At 136x it is still a weak object.  187x shows a large, very elongated galaxy with a brighter, wide middle.  250x gives very good views with averted vision.  At 272x the galaxy is long, though starting to fade.
 http://www.ngcicproject.org/dss/n/6/n6433.jpg

eg 6446:  0'.7 x 0'.6:  Vis. 15.2; SB 14.1:  47 was spotted at 100x, being oval, housing a bright
eg 6447:  1'.6 x 0'.9:  Vis. 12.8; SB 13.1:  middle, and showing a stellar core.  187x gives a good view with averted vision, and 46 can now be glimpsed preceding the main galaxy.  It was quite small, faint, round with a stellar core.  Both objects were best at 200x.  A triple star system south following was noteworthy, but very faint.
 http://www.ngcicproject.org/dss/n/6/n6446.jpg

eg 6485:  1'.5 x 1'.4:  Vis. 12.9; SB 13.6:  Spotted at 136x, south preceding a 9.5 mag. star.  187x shows a bright object, pretty large, with a stellar core.  Though listed as round, it appears to flare to oval with averted vision.  250x shows a very bright center.  It is large and now looking pretty round.
 http://www.ngcicproject.org/dss/n/6/n6485.jpg
  
eg 6486:  0'.8 x 0'.8:  Vis. 14.3; SB 13.9:  87 is easy to spot at 100x, and 86 pops out at 136x.  Both
eg 6487:  1'.8 x 1'.8:  Vis. 11.9; SB 13.1:  galaxies are seen well at 187x and 250x.  There are stellar cores on both.  86 is noticeably smaller and fainter, but still quite easy to spot with averted vision, in the same field with 87.
 http://www.ngcicproject.org/dss/n/6/n6486.jpg

UGC 11017:  1'.2 x 0'.7:  Vis. 13.9; SB 13.6:  Located without difficulty at 187x, it is large, oval, and pretty bright with averted vision.  It is located just following a mag. 10 star, and precedes eg 6486 and 6487.

eg 6504:  2'.2 x 0'.5:  Vis/SB 12.6:  Spotted at 60x!  There is a stellar core seen at 100x, and the galaxy is bright and elongated.  At 136x and 187x it is very large with averted vision.  It is very bright now.  It was viewed well at 250x and 272x, and even at 375x.  It is now very long, very extended, and still very bright.  Easy to locate, it lies along the base of a bright stellar triangle.  A nice catch in a 12" scope!
 http://www.ngcicproject.org/dss/n/6/n6504.jpg

Uranometria Chart 49 

oc DoDz 9:   28'; 15*s:  At 60x this is a big and bright, very loose cluster, pretty rich in bright stars.  There is a milky haze in the background.  83x fills the eyepiece with bright stars, like a fireworks explosion!  This is a decent object in a 12", and likely in an 8" one, too.

eg I. 1277:  1'.2 x 0'.9:  Vis. 13.4; SB 13.3:  This galaxy is small and faint at 136x, and begins to fade away at 187x.  A pair of bright double stars separate it from eg 6575 (see below).

eg 6575:  1'.7 x 1'.3:  Vis. 12.4; SB 13.2:  The galaxy is round and bright at 136x, and very easy to see.  2 faint stars zigzag from it, pretty close.  At 187x views are very good, and the galaxy appears slightly oval.  250x also gives good views.
 http://www.ngcicproject.org/dss/n/6/n6575.jpg

eg I. 1279:  2'.6 x 0'.6:  Vis. 13.5; SB 13.8:  Seen at 136x and confirmed at 187x, it appeared as a faint, large oval.  It precedes 3 stars that curve around it.  200x and 250x give occasional glimpses of a very long, faint needle galaxy.
 http://cseligman.com/text/atlas/ic12a.htm#ic1277

eg 6585:  1'.9 x 0'.4:  Vis. 12.9; SB 12.5:  Located not far from Vega, which is 24' following and just a bit south.  The central oval of this galaxy was glimpsed at 100x, and appears more elongated at 136x.  Views were good at 187x, showing a bright middle and much fainter elongation.  The galaxy is located in the north preceding end of a bright north/south stellar asterism, and just south preceding a 4-star diamond pattern.

#114 Hercules NGC Project Part 8: Uranometria Chart 51

The Hercules NGC project kept me busy for three summers, but finally ended in 2017.  Later in the year I also completed the Pegasus observing program, which will entail another massive blog effort to report everything seen on that NGC list.  My autumn observing program now solely consists of the NGC objects in Cetus, and double stars in Cassiopeia.  I am preparing Orion objects for winter observing, and hope to continue with Leo in the early spring, and Bootes in the late spring.  I am using an Orion 12" push-to Dob.

Hercules:  Uranometria Chart # 51

eg 6161:  0'.7 x 0'.3:  Vis. 14.7; Surf. Br. 12.9:  62 shows up at 136x, being oval and pretty bright. 
eg 6162:  0'.9 x 0'.7:  Vis. 13.6: Surf. Br. 13:  up at 136x and 187x.  It is very elongated, located
eg 6163:  0'.8 x 0'.5:  Vis. 14.4; Surf. Br.  13.2:  south of 62, and further from it than 63.  63 is seen at 187x,appearing like a smaller, fainter version of 62, and immediately following (but separate).  It's like an after image.  Star 26, mag. 6.5, makes finding 61 tricky, as it is closest to that star.
 http://www.ngcicproject.org/dss/n/6/n6161.jpg

eg 6177:  1'.7 x 1'.2:  Vis. 13.6; SB 14.2:  77 was seen at 136x.  It was very large, oval, pretty
eg 7179:  0'.4 x 0'.4:  Vis. 15.5; SB 13.4:  bright, and immediately preceding a bright star.  Viewed at 187x, 200x, and 250x, a stellar core is noted, plus 2 stars in the envelope, all in a line through the centre of the elongations.  A bright star north hampers views of 79, which appears stellar even at high power.


http://www.ngcicproject.org/dss/n/6/n6179.jpg

eg 6185:  1'.2 x 0'.9:  Vis/SB 13.4:  Spotted at 100x, it resembled a faint, fuzzy stellar companion to a bright star, north.  At 136x it is big and pretty bright.  At 187x and 250x it is pretty big, very oval, and the middle is much brighter.  It reaches nearly to the bright star, north. 
http://www.ngcicproject.org/dss/n/6/n6185.jpg


eg 6194:  1' x 0'.8:  Vis. 13.8; SB 13.4:  Spotted at 100x, it is tiny, round and bright.  At 136x it is larger, with a very bright centre.  At 187x and 250x the galaxy shows a stellar core.  It is slightly oval, remarkably bright, but not too large.
 http://www.ngcicproject.org/dss/n/6/n6194.jpg

eg 6196:  2' x 1'.2:  Vis. 12.9; SB 13.7:  My second triple group of the evening!  96 was seen at
eg 6197:  1'.3 x 0'.5:  Vis. 14.6; SB 14:  100x, and on up to 200x.  It is very bright, oval, and
eg I. 4614:  0'.8 x 0'.6:  Vis. 14.3; SB 13.4:  considerably smaller than its given size.  97 was spotted at 136x, and also viewed at 187x and 200x.  It is just north of a bright star, but only its oval centre could be seen.  The extensions were too faint.  The IC galaxy was very faint, appearing round at 187x and 200x.  These galaxies are all just south preceding Messier 13.
http://www.ngcicproject.org/dss/n/6/n6196.jpg
I. 4614 is in the north.

gc 6205/Messier 13:  20'; Vis. 5.8; Br. * mag. 11.9:  Though viewed many times previously, this was the official observation with the 12" Dob.  At 60x the globular cluster is already resolving all across its huge, bright surface.  The cluster is framed by 2 bright stars, with the north one coloured a rich yellow, and the fainter, south one white.  M 13, the 2 stars, and nearby bright galaxy 6207 (see below) all fit into the field of view!  At 100x the outer areas resolve into lines and curls of stars, giving the impression of rotation.  There are 2 notable extensions towards the white star, south, and another one towards eg 6207, north.  At 136x the massive core is breaking up, with many stars resolving at the very centre.  187x gives a superb view, nearly filling the eyepiece with stars.  The centre is dense and complex.  At 200x and 250x there are now dark spaces in the very core.  A "Z" line of resolved stars is at the very enter.  At 272x and 375x the dark lanes throughout the cluster are as interesting as the resolved stars.  A truly amazing and wonderful object!!
http://www.ngcicproject.org/dss/n/6/n6196.jpg
Can you spot eg 6207 north following??

 eg 6207:  3' x 1'.3"  Vis. 11.6; SB 13:  Undoubtedly the showpiece galaxy in Hercules.  It can be seen at 60x along with M 13 in the same field.  Though bright and large, it still appears rather insignificant next to the globular cluster.  100x shows significant elongation and a stellar core.  At 136x a few very faint stars can be seen just south.  The galaxy is seen steadier now, and larger and longer.  At 187x and 200x more galaxy shows preceding the core area than following it.  At 250x and 272x a very faint star follows the core, with another just north following it.  The preceding area of elongation appears clumpy. 


 http://www.ngcicproject.org/dss/n/6/n6207.jpg

eg 6195:  1'.5 x 1':  Vis. 13; SB 13.4:  Spotted at 136x, the galaxy is very conspicuous between 2 faint stars.  At 187x it shows a bright centre, with fainter parts flaring oval towards the framing stars.  At 250x it is still pretty bright and pretty large.
http://www.ngcicproject.org/dss/n/6/n6195.jpg

eg 6212:  0'.7 x 0'.4:  Vis. 14.2; SB 12.6:  Glimpsed at 187x, then again at 200x and 250x.  It was small, faint, oval, with a stellar core.  Best seen at 250x with averted vision.  It sits south of a conspicuous triangle of stars.  I used a hand-drawn detailed map to locate and identify the galaxy, based on Deep Sky Objects Browser.

#113 Hercules NGC Project Part 7: Uranometria Chart A-3

Uranometria close-up Chart A-3 contains portions of regular Charts 35 and 51.  The close up chart will be divided into three segments for the purpose of my reporting:  Abell 2197, Abell 2199, and those galaxies outside the Abell circles.

ABELL 2197 

eg 6138:  0'.9 x 0'.2:  Vis. 14.7; SB 12.7:  Very difficult to see, it was elusive and only glimpsed on occasion with averted vision.  The faint, oval slash was seen at 187x, 200x, and 250x.
http://www.ngcicproject.org

eg 6145:  0'.8 x 0'.4:  Vis. 14.2; SB 12.8:  Spread over 2 nights in late Spring 2014.  46 is easy
eg 6146:  1'.3 x 1'.1:  Vis. 12.5; SB 12.8:  to view at 100x, preceding a faint star.  It was oval and
eg 6147:  0'.4 x 0'.4:  Vis. 15.1; SB 13:     bright even up to 200x.  Many bright stars are in the field, as well as6145. Spotted at 125x and viewed up to 200x, it was best at 150x.  Averted vision shows a pretty big object.  Due to deteriorating conditions on the first night, I was unable to locate 6147.  However, the next observable night was much better, and it was spotted at 187x.  It was small, though sometimes flaring into 6145 and almost seeming as one object.  It is extremely faint and pretty difficult to see.  Wait for the best conditions.


http://www.ngcicproject.org
eg 6160:  1'.8 x 1'.5:  Vis. 13.2; SB 14.3:  Once the moon had set I began to pick off galaxies left and right.  This was seen at 100x, but it was much better at 150x, showing a stellar core.  At 187x it was getting faint, but it was large.  200x proved too faint.
http://www.ngcicproject.org

UGC 10407:  0'.7 x 0'.6:  Vis. 13.7; SB 12.7:  Both galaxies are in the north of Abell 2197. 
UGC 10415:  0'.9 x 0'.8:  Vis. 13.8; SB 13.3:  Though brighter than some of the recent NGC objects, they are not bright.  407 is much easier to view.  Both are round.  415 appears not only fainter, but smaller.  However, it did show a brighter middle.  Best views of the pair together were with averted vision at 150x.

eg 6173:  1'.9 x 1'.4:  Vis. 12.1; SB 13.2:  It appears very large and bright at 150x.  It can best be seen at 187x, once the mag. 7 double star was out of the field of view.  This is the brightest galaxy in Abell 2197, and 2nd brightest on Chart A-3.  It was slightly oval and had a notable and large bright middle.
http://www.ngcicproject.org

eg 6174:  0'.4 x 0'.4:  Vis. 14.5; SB 12.5:  This one is tricky.  However, since it lies just north of 6173, ti proved doable.  it wa tiny, almost stellar, and faint.  It was seen at 187x and 200x.

eg 6175:  1'.3 x 0'.8:  Vis. 13.7; SB 13.6:  Located at 100x, though best at 187x.  It was elongated.  It is south preceding the 7 mag. star near 6173, which lies just north of this galaxy.  All of the galaxies in Abell 2197 (except the first one) were located by star-hopping from 6146.  That one has served as home base for my explorations.  75 has a bright middle.
http://www.ngcicproject.org

eg 6180:  0'.9 x 0'.6:  Vis. 14.1; SB 13.5:  I was pleasantly surpised when this galaxy was located without much fuss, though it took 150x to confirm it.  It was seen well at 187x, displaying a bright middle.  
http://www.ngcicproject.org

eg 6184:  0'.8 x 0'.5:  Vis. 14; SB 12.9:  Sighted at 187x, it was very elongated towards long and thin.  Seen best with averted vision. 


 http://www.ngcicproject.org

ABELL 2199  

UGC 10381: 1'.2 x 0'.7:  Vis. 13.7; SB 13.4:  Located in the preceding end of Abell 2199, the galaxy was observed at 150x and 187x.  It was large, very elongated, but faint and indistinct.  It lies just within the Abell cluster.

eg 6158:  0'.9 x 0'.6:  Vis. 13.7; AB 13.1:  Not exactly a beacon of light, but compared to some of the tiny companions to eg 6166 (see below), it wasn't too bad.  It lies in the same 100x field of view as 6166, and in a larger scope no doubt all 6 galaxies could be glimpsed at once.  This one is oval and pretty dim, but at 187x it showed a brighter middle.  Best seen with averted vision.
http://www.ngcicproject.org

eg 6166:  1'.9 x 1'.4:  Vis. 11.8; SB 12.8:  There are six NGC galaxies at the center of Abell 2199. These six are very close.  66 was spotted easily at 60x.  It was pretty bright, pretty large, and noticeably oval.  100x and 150x showed it well.  2 cxompanion galaxies were seen at 150x.  However, at 187x, 200x, and 250x all 4 faint companions were spotted in the same field.  Recommended!
eg 6166A:  0'.4 x 0'.2:  Vis. 14.4; SB 11.5:  Not that difficult to spot, and very close to the main galaxy.
eg 6166B:  0'.4 x 0'.3:  Vis. 14.9; SB 12.4:  This one was tricky to see, and took some time.  It was a very transparent sky tonight (July 23rd/14).
eg 6166C:  0'.4 x 0'.4:  Vis. 13.3; SB 11.3:  Not difficult to see at higher power using averted vision.
eg 6166D:  0'.5 x 0.5:  Vis. 14.8; SB 12.4:  Not difficult, and seen at 150x.  Make certain you take some type of diagram to help identify these small galaxies.  I usually use my own hand-drawn one, using Deep Sky Objects Browser.
http://www.ngcicproject.org
 
NB:  66A= MCG-050
         66B=MCG-076
         66C=MCG-048
         66D=MCG-056

Other Galaxies On Chart A-3

UGC 10349:  1'.4 x 0'.5:  Vis. 13.6; SB 13:  Viewed at 125x and 150x, this is an impressive, very elongated slash with averted vision.  Later seen at 100x, in a triangle with 2 faint stars.

eg 6129:  0'.8 x 0'.8:  Vis. 14; SB 13.5:  I needed a hand-drawn sketch of the area, as this galaxy is out there on  its own.  It was spotted at 150x and 187x.  It wa faint, but not terribly so.  It was round and actually pretty large.  It is shown at the bottom of Chart A-3, and is in Corona Borealis.
http://www.ngcicproject.org

eg 6131:  1' x 1':  Vis. 13.3; SB 13.1:  A very, very faint object, due to its close proximity to a mag. 9 star.  A mag. 14 (?) star lay very close, just preceding.  Also in Corona Borealis.
http://www.ngcicproject.org

eg 6141:  0'.3 x 0'.3:  Vis. 14.9; SB 12.1:  This object would be much harder to locate were it not for the Uranometria close-up chart.  It was tiny, round and faint, but seen distinctly at 187x, 200x, and 250x.  Huzzah!
http://www.ngcicproject.org

UGC 10367: 1'.4 x 1'.2:  Vis. 13.3; SB 13.7:  Best seen with 100x and 125x, this one is big, very faint, and only slightly oval.  it is the brightest of 5 UGC galaxies I chose to observe on Chart A-3.

oc DoDz 5:  27':  And now for something completely different!  This large, loose group of bright stars lies just south of Abell 2199.  About 15 stars were counted at 43x and 60x.  Following is a similar size group with about 20 stars, all much fainter than the main cluster.

eg I. 4610:  0'.6 x 0'.6:  Vis. 13.8; SB 12.5:  The galaxy is very faint and ghostly at 150x and 200x.  It is round, and only seen with averted vision.

More Hercules updates coming soon!  Clear skies!

#112 Hercules NGC Project Part 6: Uranometria Chart A-9

The 26 closeup charts in the all-sky edition of Uranometria are my favourite thing about this atlas.  I only wish there were 25 more!  Chart A-9 is called "Hercules Galaxy Cluster, A 2151."  It contains portions of regular Charts 69, 88, and 87.  In addition to Abell 2151, three other Abell galaxy clusters are included, as well as a number of other nearby galaxies.  I managed to find all of the NGCs and ICs on this chart, and several UGCs and MCGs.  So here we go....

ABELL 2151

eg 6040:  1'.4 x 0'.5:  Vis. 14.2; SB 13.6:  6040 is very elongated, even at 136x, and fairly bright
eg 6040B: 0'.8 x 0'.8: Vis. 14; SB 13.4:   with averted vision.  40B is round, and not too small.  It sits very close to 40, south, and both are close to the 6041 pair.  Even at high power (200x) I can see 5 galaxies!  All are seen best with averted vision.
http://www.ngcicproject.org
eg 6041A:  1'.2 x 1'.1:  Vis. 13.3; SB 13.5:  41A is bright and easy at 187x, appearing elongated to
eg 6041B:  0'.3 x 0'.3:  Vis. 15.6; SB 12.9:     the south.  At 200x and 250x, 41B is glimpsed just south.  It has a stellar core, and a tiny bit of space between it and the main galaxy.  41A is pretty large and bright; 41B is tiny and round, showing mostly its bright core.

eg 6042:  0'.8 x 0'.7:  Vis. 13.9; SB 13.2:  The 5th of 5 galaxies seen tonight (June 23rd, 2016) in a very tight area.  All 5 are located south following a 6.5 mag. star.  42 is quite small and faint, as viewed at 136x and 187x.  It was somewhat easier to see at 200x and 250x, though still very small.

eg 6044:  0.6 x 0.6:  Vis. 14.3; SB 13:  100x gives a possible sighting of a suspicious object.  125x clearly shows a small, faint, round galaxy.  150x and 187x show it considerably better, looking like a ghostly planetary nebula.  200x shows a bright center, but overall it is fading in this range.
http://www.ngcicproject.org

eg 6043A: 0'.5 x 0'.5:  Vis. 14.3; SB 12.7:  43A was not difficult with averted vision at 150x.  6045
eg 6045:   1'.3 x 0'.3:  Vis. 13.9; SB 12.8:   was challenging and difficult to see steadily.  6047 was
eg 6047:   0'.8 x 0'.8:  Vis. 13.5; SB 13.1:    tricky due to a 12 mag. star close to it.
http://www.ngcicproject.org

eg 6050:   0'.8 x 0'.5:  Vis. 13.5; SB 13.1:  This was oval, quite faint, but not that small.  It was seen also at 200x and 250x.  The object is actually a pair of intersecting galaxies seen face-on, though it appears as one object to the eye.
http://www.ngcicproject.org
eg 6054:  0'.7 x 0'.4:  Vis. 15.2; SB 13.7:  82 was the least difficult, seen pretty well at 187x, 200x,
eg I. 1182: 1' x 0'.5:  Vis. 14.2; SB 13.3:   and 250x.  It was large, bright with averted vision, and
eg I. 1184: 0'.8 x 0'.4: Vis. 14.2; SB 12.9:  oval.  It was further from the 12 mag. star which all 3 galaxies are near.  54 was located by finding 6050, then letting the much smaller and fainter galaxy pass by in the field.  84 came past the field almost immediately following 54, with the 12 mag. star barely south and in between them.  54 was seen at 250x with averted vision, close to the star; 84 is small and tricky, a tiny oval ghost shape at 250x with averted vision.

eg 6055:  1' x 0'.6:  Vis. 13.7; SB 13:  55 was seen well at 125x.  It was oval, and though not 
eg 6057:  0'.6 x 0'.5: Vis. 14.7; SB 13.4:   terribly bright, it wasn't that hard to spot.  57 was first seen at 150x, immediately following 55.  187x and 200x show the smaller one as round.  It was very small, and best with averted vision.

http://www.ngcicproject.org

eg 6056:  0'.9 x  0'.5:  Vis. 13.9; SB 12.9:  Confirmed at 125x, it was seen best with averted vision as an elongated slash.  It was noticeably brighter at 150x, especially the center.  187x gave the best view, showing a fairly large slash.  It was fading at 200x, except for the center.
http://www.ngcicproject.org

eg I. 1178:  1'.2 x 1'.1:  Vis.  14; SB 14.1:  Viewed at 136x and 187x.  It was pretty faint, between two stars, and near avery faint star.


ABELL 2147 and 2152 

There are no NGC objects in these clusters, though 47 has an IC.  I managed to find 3 objects in 47, and 2 in 52. 

ABELL 2147
 eg I. 1165:  0'.8 x 0'.5:  Vis. 14.2; SB 13.1:  Viewed at 136x and 187x, and not too bad at 250x.  It is very oval, not snall, but pretty faint.  It lies within a checkmark star pattern.  These stars are all very faint.  the galaxy, along with the following 2 stars, are withing Abell 2147.

eg UGC 10143:  2' x 1'.1:  Vis. 13.1; SB 13.9:  Observed well at 136x, 187x, and 250x, this galaxy is a nice big oval with a star involved.  It lies not far from another faint star.  It is pretty large and pretty bright, and was definitely the best of the evening.  How did the NGC and IC surveys miss it?

eg C108-81:  0'.8 x 0'.4:  Vis. 14.1; SB 12.7:  Viewed at 187x and 250x, it is very faint and very small.  It is slightly oval, and has 2 faint stars following.  Use averted vision.

ABELL 2152
eg M+3-41-83:  0'.8 x 0'.8:  Vis. 13.8; SB 13.4:  Spotted at 136x, it is a bit easier to view than 41-95, below.  It is still pretty faint.  187x shows it as pretty large compared to 41-95.  It begins to fade at 200x.

eg M+3-41-95:  0'.8 x 0'.8:  Vis. 14.3; SB 13.8:  Spotted at 136x, but it is elusive.  It is involved with or is very near to a faint star, sometimes giving it an ovalish appearance.  187x and 200x give satisfactory views, though it is small and faint.  It is near a mag. 12 (?) star.  One other galaxy lies within Abell 2152 on the Uranometria chart, but I did not attempt it at this time.

The Rest of the Galaxies 

These galaxies are lie outside the Abell circles on Chart A-9.  I will list them in order of R.A. 

eg I. 1151:  2'.5 x 0'.8:  Vis. 12.9; SB 13.6:  Positioned on the far preceding edge of Chart A-9, this galaxy lies within Serpens Caput.  It was large, elongated, and pretty faint, but decent views were had at 125x and 150x.  Worth a stopover. 

eg I. 1155:  0'.9 x 0'.7:  Vis. 14.3; SB 13.6:  It lies just preceding Abell 2147, and sits just within Serpens Caput.  It was spotted at 136x, north preceding a 7.9 mag. star.  The galaxy appears oval at 187x, and is best seen with averted vision.  It is pretty faint, but not too small.

eg NGC 6028:   1'.3 x 1'.2:  Vis. 13.5; SB 13.8:  6028 was observed well at 150x and 187x.  It was
eg M+3-41-33:  0'.9 x 0'.8:  Vis. 13.7; SB 13.3:  faint, though brighter and larger than the M+3 galaxy.  M+3 seemed easier when at lower powers, but at 150x and 187x it appeared smaller and not as bright as 6028.  Both sit amongst a nice star field.
http://www.ngcicproject.org
The M+ galaxy is out of the field, north of the bright star.

eg 6030:  1'.1 x 0'.8:  Vis. 12.8; SB 12.5:  The sighting was confirmed at 100x, where it appeared pretty bright, large, and oval.  Views were very good at 150x and 187x.  Though the galaxy began to fade at 200x, a stellar core was now noted, surrounded by brighter haze and then an outer, fainter envelope.  This is one of the better galaxies on Chart A-9.
http://www.ngcicproject.org

eg M+3-41-47:  0'.7 x 0'.5:  Vis. 13.8; SB 12.7:  Spotted at 100x, it resembled a tiny planetary nebula.  More size was evident at 187x, where it became oval.

eg 6034:  1'.1 x 0'.8:  Vis. 13.5: SB 13.4:  Confirmed at 125x, the galaxy lay close to a 13 mag. (?) star.  It was seen best with averted vision, even at 200x.  It was oval at high power.
http://www.ngcicproject.org

UGC 10195: 1'.5 x 0'.4: Vis. 14; SB 14.7:  At an average mag. of 14.35, this is one of the fainter objects ever picked off the Aragorn Observatory!  Itwas elongated at 150x and 200x, ghostly and flaring with averted vision.

eg 6061:  1'.1 x 0'.8:  Vis. 13.6; SB 13.2:  The galaxy is oval, faint, and cradled by 3 faint stars south.  Though less than impressive, it was observed at 100x, 125x, 150x, and 187x.  Just north is R Hercules.  On my visit (July 15th/15) the variable star was a ruddy colour, and approx. mag. 11.
http://www.ngcicproject.org

UGC 10204: 1' x 0'.6: Vis. 13; SB 12.3:  If this galaxy wasn't so close to a 7.9 mag. star it would be a rather good object, and likely on the NGC list.  Even so it is a pretty bright galaxy.  Spotted at 100x, it appeared better at 136x.  It is oval and has a bright stellar core.  At 187x and 200x the galaxy is still very bright, and very oval.

eg 6073:  1.3 x 0'.7:  Vis. 13.5; SB 13.3:  Spotted at 100x and 136x, it was oval and pretty faint.  Situated between a 10.5 mag. and an 11.5 mag. star, it is closer to the brighter one.  At 187x and 200x it appears very oval.  It now shows a brighter middle and possibly a stellar core.
http://www.ngcicproject.org

eg M+3-41-141: 0'.9 x 0'.4:  Vis. 14.4; SB 13.2: Spotted at 136x (!) and 187x, it was very oval, pretty faint, and not too small.  the center is noticeably brighter.  It is preceding a mag. 11.5 star.

#111 Hercules NGC Project Part 5: Uranometria Chart 67

Chart 67 takes us up the border with Lyra, Vulpecula, and Aquila.  The Hercules area is rich in galaxies and double stars.  I include a few IC and UGC objects if they are near any NGC I am seeking, and if their stats indicate it being worth a peek.

eg 6547:  1'.5 x 0'.4:  Vis. 13.6; SB 12.9:  At 100x I noticed a suspicious haze, like a slash.  150x confirmed it, with a star possibly involved.  Though 187x gives a good view, a nearby star interferes with the galaxy sight.  At 200x and 250x the galaxy is still pretty bright and very elongated.
http://www.ngcicproject.org

eg 6548:  3' x 2'.8:  Vis. 11.7; SB 13.9:  48 turned out to be the night's showpiece, visible at 100x.
eg 6549:  1'.4 x 0'.4:  Vis. 13.8; SB 13:  It was large, with a stellar core and 2 levels of surrounding haze.  It appeared round.  It was viewed well as high as 250x, where it remained quite bright.  49 was confirmed at 125x but only the center was seen.  It was difficult to see the slash, even at 200x.
http://www.ngcicproject.org

eg 6555:  2' x 1'.5:  Vis. 12.4; SB 13.4:  Spotted at 60x and 100x, but it is pretty faint.  It is pretty large, however.  136x shows the oval shape well with averted vision.  At 187x it is faint, but still pretty impressive with averted vision.  It is fading at 272x, though still large.  It has a stellar core.
http://www.ngcicproject.org

eg 6571:  0'.4 x 0'.4:  Vis. 14.4; SB 12.5:  It took several sweeps to finally locate this small, faint galaxy.  It was eventually spotted at 200x.  It was round and ghostly with averted vision.  250x also showed it.  After this it seemed to show well even at 187x, and finally, I could just barely make it out at 150x.
http://www.ngcicproject.org

eg 6576:  0'.4 x 0'.4:  Vis. 13.8; SB 11.6:  77 was seen at 150x.  Though pretty small, it was bright,
eg 6577:  1'.5 x 1'.3:  Vis. 12.3; SB 13.5:  especially the center.  It sits very near to a faint star, following.  200x, 250x, and 300x show a stellar core.  76 was seen with averted vision at 150x.  It appeared stellar when using direct vision, but averted vision showed nebula on occasion.
http://www.ngcicproject.org

eg 6579:   0'.4 x 0'.4:  Vis. 13.8; SB 11.6:  This was the third of 4 galaxy pairs seen in one night's eg 6580:  1'.3 x 0'.7:  Vis. 13.3; SB 13.2:  session.  80 was confirmed at 150x, being hazy, elongated, and very near a bright star, north.  It becomes a double galaxy at 187x and higher.  79 is a bit further south from the nearby star.  Both have stellar cores.  Fun!
http://www.ngcicproject.org

eg 6581:  0'.6 x 0'.3:  Vis. 14.9; SB 12.9:  Of the three galaxies, UGC 11156 was the easiest to spot.
eg U 11156:  1' x 1':  Vis. and SB 13.3:         It was noted at 150x, and also observed at 187x and
eg U 11155:  1' x 0'.8:  Vis. 13.9; SB 13.6:    200x.  It is pretty large and round.  UGC  11155 is much fainter, though somewhat similar, perhaps a bit oval.  It was viewed at 150x and 187x with averted vision.  6581 is a bit of a mystery.  Uranometria is the only altals to plot it where it is, using the above specs.  Others place it about 20' north, between UGC 11050 and an 8 mag. star to the north following.  I did see this version, which was faint but with a brighter center.  AT 187x and 200x it was oval.  The first 6581 seems to be round, about 0'.4 x 0'.4, and brighter than the north one.  The north one is referred to as I. 1280.  Uranometria is the only place that makes these 2 separate objects.  Other sites duplicate them, not mentioning the south one.
http://www.ngcicproject.org

eg 6586:  0'.9 x 0'.5:  Vis. 13.7; SB 12.7:  Spotted at 125x, near a 'bright' star.  150x shows a small but pretty bright cigar shape.  It was seen well at 187x and 200x, though it was best with averted vision, epsecially due to the nearby star.
http://www.ngcicproject.org

eg 6587:  1'.3 x 1'.1:  Vis. 12.9; SB 13.2.  Spotted at 100x, it was round with a bright stellar core.  150x showed a fuzzy object, similar to a small comet.  At 200x it was still bright, and near a 'bright' star, north.
http://www.ngcicproject.org

eg 6593:  0'.9 x 0'.7:  Vis. 14.3; SB 13.7:  I was able to confirm sightings at 187x, 200x, and 250x.  It was oval, faint, and in a line with two very faint stars, north.  Finding this galaxy without aid was confirmation of exceptional transparency tonight (August 12th/15).  

eg 6599:  1'.3 x 1'.2:  Vis. 12.6; SB 13:  First seen at 125x, it is situated in a small star group.  2 faint stars and 1 very faint star lie near it.  It was also viewed at 150x, 187x, 200x, and 250x.  Even so it remained round, small, but pretty bright.
http://www.ngcicproject.org
eg 6602:  0'.9 x 0'.7:  Vis. 13.3; SB 13.1:  Following a line from a south preceding mag. 9 star thru eg 6599 and extending it the same distance north following, I was able to locate this galaxy at 150x.  It is faint, slightly oval, and has a faint star preceding it.  Views are still decent at 187x and 200x, though best with averted vision.
http://www.ngcicproject.org

eg 6616:  1'.4 x 0'.6:  Vis. 13.8; SB 13.5:  Confirmed at 187x, it resembled a fuzzy, dim star.  It was seen better at 200x, and was even quite oval at 250x.  The galaxy lies very near a bright star, south preceding.
http://www.ngcicproject.org

UGC 11197:  1'.1 x 1'.1:  Vis. 13.3; SB 13.4:  Lying a degree south of eg 6616 and a bit following, it was spotted at 100x.  It is seem best with averted vision because of an 8.5 mag. star south preceding.  The galaxy is round, with a pretty bright middle and a gainter outer envelope.  Good views were had at 187x.

eg 6619:  1'.2 x 1'.1:  Vis.  13; SB 13.3:  This galaxy, along with 6623, were the brightest ones of the night (Aug. 12th/15).  Randy G. observed with me.  Both galaxies can be seen at moderate powers.  19 was easily spooted at 100x, making a rough triangle with 2 close stars of near equal mag.  The galaxy appeared round, with a very bright core.  A 14 mag. star is conspicous at 200x, and another even closer to the envelope.  250x gave decent views.
http://www.ngcicproject.org

eg 6623:  1'.3 x 1'.2:  Vis. 13; SB 13.5:  A near twin to nearby 6619!  They can be viewed together at 100x, 125x, and 150x.  It shows a stellar core.  Very good views were had up to 250x, where several faint stars were observed near the outer envelope (one of these may have been the MCG galaxy!).
http://www.ngcicproject.org

eg 6628:  1'.9 x 1'.3:  Vis. 12.9; SB 13.8:  Spotted at 100x, it was elongated.  It sits immediately preceding a mag. 9 star.  Weird, but that is all I said about it.
http://www.ngcicproject.org

eg 6632:  3' x 1'.4:  Vis. 12.1; SB 13.5:  A remarkable object, and observed from 60x through 250x.  At 60x and 100x, views were best with averted vision.  It was large, dim, and oval.  At 150x it was difficult to block glare from a nearby 5.5 mag. star, south.  At 187x, 200x, and 250x it was decent, and nearly involved with a faint star, preceding.
http://www.ngcicproject.org

eg 6641:  0'.9 x 0'.7:  Vis. 13.4; SB 12.7:  Spotted at 100x and confirmed at 150x, ti was oval.  187x gives a pretty good view.  The galaxy is pretty large, but sits near a relatively bright star.  It was fading at 200x, but quite oval.
http://www.ngcicproject.org

eg 6658:  1'.7 x 0'.4:  Vis. 12.9; SB 12.4:  Glimpsed with averted vision at 100x, the galaxy was a long, thin, very faint slash.  This is not an object that compares well to its listed mag.  It was seen at 150x and 187x, and was okay to view at 200x with averted vision.  It appears to be involved with a faint star, or perhaps had a bright core, or both.
http://www.ngcicproject.org

eg 6661:  1'.7 x 1'.1:  Vis. 12.1; SB 12.6:  Noted at 100x, it was very bright. 150x showed the oval shape.  It sits in a pretty bright starfield, making initial discovery a bit tricky.  At 187x it is large and medium bright.  Though fading at 200x, it shows a stellar core.
http://www.ngcicproject.org

eg 6669:  0'.9 x 0'.9:  Vis. 15.1; SB 14.7:  One of those mystery objects.  The image below identifies a tight and very faint asterism, which could be what Herschel actually saw.  However, at the location on Uranometria is a faint galaxy.  See the Deep Sky Objects Browser for what I saw.  A round haze, involved with a faint star, is nearly impossible to see, even if the exact location is known.  Seen with averted vision at 200x and 250x.  It is the 4th star in a faint line curving south (not the 5th star, which looks hazy but is actually a close triple star).  I sincerely doubt that Herschel saw the galaxy--the close triple seems more likely.
http://www.ngcicproject.org

eg 6674:  4' x 2'2:  Vis. 12.2; SB 14.4:  Not even visible to me on the last evening, tonight it was quite apparent and lovely!  Spotted at 60x, it was faint, ghostly, and large.  100x shows it as a nice object, though in this range it is a challenge to view it with the 8" stop in place.  A faint star is preceding.  The galaxy is very elongated, with a brighter central area, though the outer elongated envelope is clearly visible.  187x and 200x show 3 stars possibly involved.  It fades overall at 200x, but the central oval is still bright.
http://www.ngcicproject.org

eg 6680:  0'.7 x 0'.4:  Vis. 14.6; SB 13.1:  Spotted at 150x, and also viewed at 200x and 250x.  A small, elongated hazy smudge was noted immediately south of a 10.5 mag. (?) star.
http://www.ngcicproject.org

eg 6697:  1'.2 x 1'.1:  Vis. 12.7; SB 12.9:  Spotted easily at 100x, it was round.  150x reveals a very bright core.  187x and 200x appear to show a star imbedded in the following end.  At 200x and 250x the galaxy is still bright and a good object for a 12" scope.
http://www.ngcicproject.org

UGC 11346:  1' x 0'.7:  Vis. 13.7; SB 13.2:  Lying south preceding 6697, this galaxy i very small and very faint, seen at 200x with averted vision, where it barely shows.  It was slightly improved at 250x, where it finally appeared to be oval and a bit larger.
