#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.

#110 Hercules NGC Project Part 4: Uranometria Chart 68

This is a busy chart, so I will do it in 2 sections, both seen below.

Chart 68, Right Side 

eg 6201:  0'.3 x 0'.2:  Vis. 14.6; SB 11.4:  Using a hand-drawn detailed star chart (I use Deep Sky
eg 6203:  0'.6 x 0'.6:  Vis. 14.4; SB 13.1:  Objects Browser, an excellent on-line resource), I eventually found the correct area to search.  Both galaxies can be glimpsed at 187x.  6903 is larger and easier to see, though it appears stellar at times.  6201 is stellar at 187x.  250x, 272x, and 378x give good glimpses of 6903, using averted vision.  In this range even 6201 improves somewhat.  It is very small with averted vision.  Both galaxies are close to pn 6210.  A 16" would be a much better search tool.



http://www.ngcicproject.org


pn 6210:  21"; Vis. mag. 8.8; Cent. * mag. 12.6:  Spotted at 60x, it is an incredibly bright object,and fun to observe.  A filter is not needed.  The central star is not easy to distinguish because of the overall brightness.  I was able to observe the nebula up to 500x, one of the very times I use this high a magnification.  It appears oval and pretty large at 375x and 500x.  There seems to be fainter edges.  The object is almost football-shaped.  It was seen well back in the old 8" days, and no doubt can be viewed with a 6".
http://www.ngcicproject.org

eg 6228:  0'.9 x 0'.5:  Vis. 14; SB 13.3:  I needed another diagram for this faint object.  Observed at 136x (barely), it is a very faint cigar at 187x and 250x.  It is pretty small.
http://www.ngcicproject.org

eg 6233:  1'.4 x 1'.1:  Vis. 13.3; SB 13.5:  Suspected at 100x, the galaxy sighting was confirmed at 136x.  At 187x a brighter center is noted, with fainter haze surrounding.  At 250x it is ghostly, large, and very oval.  It now shows a stellar core.  A 9.5 mag. star is just south following, making location fairly easy.
 http://www.ngcicproject.org

eg 6243:  1'.1 x 0'.4:  Vis. 14.1; SB 13.1:  Observed at 136x, 187x, and 250x.  I saw a pretty large but very faint very elongated oval.  The middle area is much brighter.  Seen best with averted vision.
 http://www.ngcicproject.org

eg I. 4630:  0'.8 x 0'.5:  Vis. 13.6; SB 12.5:  This one seemed within reach.  It was suspected at 136x and confrimed at 187x.  It has a stellar core, is very small, and very faint.  At 250x it formed a dim cigar shape.  At 272x a bright core is visible, with a much fainter surrounding envelope.  Averted vision shows it best.  Tricky to see at first.

eg 6267:  1'.3 x 1':  Vis. 13.1; SB 13.3:  Spotted at 100x, as the sky kept getting better and better tonight (July 26th/16).  At 136x the galaxy is pretty large, oval, and showing a bright center.  It is easy to spot in this range.  At 187x and 200x it is large and pretty faint.  It appears evenly lit.
 http://www.ngcicproject.org

eg 6276:  0'.4 x 0'.3:  Vis. 14.6; SB 12.2:  78 was seen at 100x, being small but very bright.  Up to
eg 6278:  2' x 1'.2:  Vis. 12.4; SB 13.2:  272x shows a very bright center, oval.  The extensions are not obvious; it just seems large and oval.  The galaxy appears significantly smaller than its given dimensions.  76 was spotted at 136x.  It is not difficult to identify, but too small to notice anything much.

eg I. 1236:  1' x 0'.8:  Vis. 13.6; SB 13.2:  Glimpsed at 100x, it is a bit easier to identify at 136x.  Seen well at 187x, it is slightly oval and pretty big.  It sits between 2 faint stars, though not directly between.  The galaxy fades at 250x, with a bright star nearby masking it (mag.7.7).

Next, a group of 8 galaxies, all located in the same half degree field.  Look between +27 and +28 degrees, and between 16 hours 56 minutes R.A. and 17 hours.

eg 6261:  1'.4 x 0'.5:  Vis. 14; SB 13.4:  Spotted at 136x.  It becomes a faint but decent slash at 187x.  Views are still good at 250x.  The galaxy is pretty wide and fairly long.  
 http://www.ngcicproject.org

eg 6263:  0'.0 x 0'.9:  Vis. 13.7; SB 13.4: Spotted at 100x, north of a faint star, and between it and a 9.3 mag. star.  The galaxy is very close to the fainter star.  Good views can be had at 136x and 187x, best with averted vision.  There is a bright stellar core.  The object is fading at 250x.
 http://www.ngcicproject.org

eg 6264:  0'.7 x 0'.5:  Vis. 14.5; SB 13.2:  65 can be spotted at 136x, preceding 6269 (below).  It is
eg 6265:  0'.9 x 0'.6:  Vis. 14.2; SB 13.4:  pretty large, very oval, and pretty bright with averted vision.  Good views were had at 187x and 250x.  6264 is much smaller and much fainter, sighted at 187x, 200x, and 250x.  It can be found north following a faint star, and only with averted vision.  It is very small and very faint.
 http://www.ngcicproject.org

eg 6269:  2' x 1'.6:  Vis. 12.2; SB 13.5:  This big, fairly bright galaxy sits at the heart of a cluster of 8 NGC galaxies.  Most are very faint.  69 was spotted at 60x.  At 100x it showed a big oval shape, pretty bright, especially the center.  136x shows a stellar core.  187x shows at least 2 very faint stars south, and another north.  200x and 250x give good views, especially of the large, central area, brighter than the outskirts.  The best object of this tight group of 8 galaxies.
 http://www.ngcicproject.org

eg 6270:  0'.5 x 0'.5:  Vis. 13.3; SB 11.9:  Don't believe the hype!  This is the most difficult of the group!  Think at least 2 mag. fainter than given.  It is very, very small and very, very faint, a threshold object at 187x, 200x, and 250x.
  http://www.ngcicproject.org

eg 6271:   0'.6 x 0'.6:  Vis. 14.1; SB 12.8:  
eg 6272:   0'.5 x 0'.2:  Vis.  14.5; SB 11.9:  Both of these galaxies were easier than 6270.  71 was not difficult using averted vision.  72 is very small and very faint.  It can be glimpsed using 187x and averted vision.  72 is not for the faint of heart.  Both are seen at 250x.
 http://www.ngcicproject.org
                                                                                                                                           

eg 6308:  1'.2 x 1'.1:  Vis. 13.4; SB 13.5:  Observed at 136x and 187x, preceding a field of faint stars.  The galaxy is large, pretty bright, and round.  It is very close to the pair 6314/15, which are just south following.
  http://www.ngcicproject.org

eg 6314:  1'.4 x 0'.7:  Vis. 13; SB 12.8:  14 is pretty large, bright, and elongated.  It was spotted at
eg 6315:  0'.8 x 0'.6:  Vis. 13.2; SB 12.3:  136x.  It just precedes a double star, a close pair and pretty faint.  6215 is small and faint, located between 6214 and a bright star.  187x shows both objects well.
  http://www.ngcicproject.org

eg 6321:  1'.1 x 1':  Vis.  and SB 13.4:  Spotted at 136x, it is small, round, and faint.  At 187x it is best with averted vision, being close to 2 stars.  It is round and faint.  Views are best at 200x.  It fades at 250x.  A bit tricky to locate.


NOTE:  For eg 6274, 6274A, 6282, 6330, 6364, 6486, 6487, UGC  11017, see blog entry for Chart 50 (forthcoming).



Chart 68, Left Side

eg I. 1256:  1'.6 x 1':  Vis. 13.2; SB 13.7:  Located at 136x, the galaxy is large, oval, and faint.  Best view is at 187x, as it is fading at 250x.  It is pretty large, though, and lies in a bright star field.

eg 6371:  0'.8 x 0'.3:  Vis. 14.3; SB 12.6:  6372 was spotted at 100x, and the much smaller and
eg 6372:  1'.7 x 1'.1:  Vis. 12.9; SB 13.4:  fainter 6371 at 136x.  72 is bright, oval, and quite easy to see, especially with averted vision.  71 was seen best at 187x, and only with averted vision.  It is small, oval, and very faint.
http://www.ngcicproject.org

eg 6408:  1'.6 x 1'.4:  Vis. 12.7; SB 13.4:  Spotted at 100x, it was pretty large, round, and very faint.  150x shows it moderately better, with a brighter center now seen.  187x gives the optimum view, showing it to be big and round, but not very bright.
http://www.ngcicproject.org

eg 6417:  1'.4 x 1'.2:  Vis. 13.1; SB 13.5:  Suspected at 100x ,the galaxy is located easily at 136x, despite its proximity to a mag. 7 star.  It is round, reasonably bright, and relatively close to the star.  It becomes more ghostly at 187x, and quite large, especially if the offending star is kept out of the field.  It appears to be evenly lit.
http://www.ngcicproject.org

eg 6427:  1'.6 x 0'.6:  Vis. 13.3; SB 13.1:  Spotted at 136x, it was round, bright, and showing a stellar core.  At 187x a few faint stars are seen very near.  Views are still good at 250x, though I am only seeing the central globe.
http://www.ngcicproject.org

eg 6429:  1'.9 x 0'.6:  Vis. and SB 13.1:  Spotted easily at 136x, it is bright and very oval.  At 187x a very faint star lies in or close to the haze.  250x gives a good view.  272x shows a bright stellar core, and good views overall.
http://www.ngcicproject.org

eg 6430:  1'.7 x 0'.5:  Vis. 13.5; SB 13.2:  Uranometria does not list the NGC number, instead calling this UGC 10966.  Other sources informed me that this is, indeed, eg 6430.  Spotted at 187x, it was very elliptical and very faint.  It is located just north of a bright star (mag. 9.5) and south of a faint asterism.  My telescope computer calls 6430 an asterism.  Interesting stuff!
http://www.ngcicproject.org

eg 6442:  1'.9 x 1'.5:  Vis. 12.6; SB 13.7:  Spotted at 100x, it appeared oval in shape.  At 150x it is pretty bright, though not very large.  187x and 200x occasionally show it as a much bigger object.  It can be found just preceding a tiny, faint triangle of stars.
http://www.ngcicproject.org

eg 6452:  0'.5 x 0'.5:  Vis. 14.4; SB 12.7:  Glimpsed at 150x and 187x, it is elusive, small, dim, and round.  It is just preceding a faint group of 3 stars.  At times the galaxy appears stellar.
http://www.ngcicproject.org

eg 6458:  1'.3 x 0'.9:  Vis. and SB 13.4:  Both galaxies can be seen at 100x.  At 150x 58 seems a bit
eg 6460:  1'.9 x 1'.1:  Vis.  13.1; SB 13.8:   brighter, and though appearing pretty large, 60 is still showing well.  It is now quite elongated, with a slightly brighter middle.
http://www.ngcicproject.org

eg 6467:  2'.6 x 1'.7:  Vis. 12.6; SB 14.1:  Spotted at 100x, it was large, oval , and very faint.  At 150x the full extent of the galaxy is trying to come through, causing flaring in all directions with averted vision.  Seen best at 187x, the galaxy is involved with several very faint foreground stars.  A possible stellar core was noted.  It sits between two relatively bright stars, the south one being double.
http://www.ngcicproject.org

eg 6482:  2' x 1'.7:  Vis. 11.4; SB 12.8:  At 60x and 100x, the galaxy looks like a very bright planetary nebula.  150x shows some very faint haze with averted vision, but the center is extremely bright.  187x, 200x, and 250x show a large, round, very faint haze surrounding an almost blindingly bright central core.  A bright galaxy but otherwise unexciting.

eg 6484:  1'.9 x 1'.9:  Vis. 12.3; SB 13.6:  Spotted at 100x and observed well at 136x.  It is very large, round, and pretty bright.  Good views were had at 187x, 250x, and 272x.  It is very large, round, pretty bright, and has a stellar core.  Also seen back in the day with the Edmund 8".

eg I. 1269:  1'.7 x 1'.3:  Vis.  12.8; SB 13.5:  Located at 100x, it was large and oval, and sitting within a bright triangle of stars, approx. mag. 11.5.  Though faint overall at higher powers, the central area stays pretty bright up to 200x.

eg 6490:  1.'1 x 0'.9:  Vis. 13.5; SB 13.3:  This turned out to be a lovely pair of galaxies, and I
eg 6495:  2'.1 x 1'.8:  Vis. 12.2; SB 13.5:  spent considerable time here.  The pair are separated by the base line of a faint triangle of stars, with the north preceding one being double.  Both galaxies were seen at 100x, but it was at 150x that the size difference really comes through.  95 appears to be a tiny bit brighter overall than 90, but not by much.  They remain in the same field of view at 187x and 200x.  Recommended with a 12".

eg 6500:  2.'2 x 1'.6:  Vis. 12.2; SB 13.4:  Despite a 7.4 magnitude star in the field, both galaxies
eg 6501:  2' x 1'.8:  Vis. 12; SB 13.3:   were seen at 100x, where they already appear to be very bright and quite large.  150x shows them as remarkably similar in appearance, and still really bright.  At 187x and 200x things remain very bright, and stellar cores are noted.  6500 now appears oval.  200x and 250x show both objects well, and they make another fine pair, worth seeking out with a 12".  I applied 300x, but it did not improve things over 250x.  Now, if it weren't for that 7.4 mag. star...

eg 6513:  1'.2 x 0'.8:  Vis. 13.3; SB 13.1:  At first I could not find it.  I looked long and hard, before finally giving up.  I came back later in the night, then realized I had been looking at the wrong two guide stars.  As soon as I found the correct spot, there it was.  The galaxy was pretty big and bright at 136x.  It was very good to view at 187x, but fading somewhat at 250x.  At high power it is very oval, and still fair to view with averted vision.

eg 6518:  0'.4 x 0'.4:  Vis. 13.9; SB 11.8:  This was an easy one!  It was located at 136x.  It lies south of a fairly bright star, and reminded me of a medium-sized planetary nebula.  At 187x views were good, with the galaxy being bright and very round.  At 250x a stellar core is noted, with a possible faint star on the preceding lip of the envelope.  The galaxy remains bright with averted vision.

eg 6527:  1'.4 x 1':  Vis. 13.4; SB 13.6:  Located at 100x, south of a mag. 11 or mag. 12 star, just following a tiny, dim mini-cluster of stars.  150x shows a bright center.  Though pretty faint at 187x and 200x, the oval shape is noted, along with a brighter middle.

I am now five days away from the next two-week observing period.  I should have time to get Chart 67 up before then.  the rest will have to wait until the August session is completed.  By then, I should also be able to report on the deep sky objects of Scutum.  Until then, clear skies!

#109 Hercules NGC Project Part 3: Uranometria Chart 69

The left side of Chart 69 includes many galaxies in Hercules.  Also present is the north half of close-up Chart A-9.  That chart will have its own blog entry soon, and so those galaxies will be omitted from this entry.

eg 6032:  1'.6 x 0'.7:  Vis. 13.5; SB 13.4:  The galaxy is large, but faint and very elongated.  It has a wide middle, and was located at 136x.  It was best seen at 187x with averted vision.
http://www.ngcicproject.org

eg 6035:  0'.9 x 0'.9:  Vis. 13.5; SB 13.1:  Round and pretty large, it is considerably brighter than 6032.  Located north of a triangle of bright stars.  32 and 35 are both fading at 200x, though 35 is easier to see.  Even so, it is a pretty faint object. 
http://www.ngcicproject.org

eg 6052:  0'.9 x 0'.7:  Vis. 13; SB 12:  Previously viewed with the 8".  Located tonight at 60x, it was bright, round, and reminded me of a planetary nebula.  It is very bright at 100x, and still round.  At 136x it begins to look oval.  It is located between two stars (midway), and there is also a faint star preceding.  At 187x and 250x the galaxy is very bright, oval, but quite small.
http://www.ngcicproject.org

eg 6060:  2'.1 x 1'.1:  Vis. 13.1; SB 13.8:  An impressive galaxy--yay!  Spotted easily at 60x, it is already big and very elongated at 100x.  Very good views are had at 136x.  At 187x and 200x it is very large and still pretty bright.  Recommended viewing.
http://www.ngcicproject.org

eg 6062:  1'.2 x 0'.9:  Vis., SB 13.6:  62 is flaring oval at 136x.  It seems pretty bright and pretty
eg 6062B: 0'.4 x 0'.4:  Vis. 15.3; SB 13.2:  large.  The center is brighter than the edges.  At 187x views are pretty good.  62B can be (barely) glimpsed at this range, south of the main galaxy and separate from it.  It has a stellar core, is very faint, small and round.

eg 6075:  0'.9 x 0'.7:  Vis. 13.9; SB 13.5:  Spotted at 100x, it was small but pretty bright ,especially when compared to 6148.  At 136x I noticed a stellar core.  There are good views at 187x.  At 200x it appears oval, and it is fading at 250x.
http://www.ngcicproject.org

eg 6084:  1' x 0'.6:  Vis. 13.9; SB 13.2:  This one is tricky to see due to its proximity to a mag. 10 star.  I searched everywhere else first, then finally spotted it just north following the bright star.  A very faint oval was glimpsed with averted vision at 187x and 250x.
http://www.ngcicproject.org

eg 6098:  1' x 0'.7:  Vis. 13.3; SB 13:  Seen at 136x as one long oval object.  It is rather faint.  At 
eg 6099:  0'.9 x 0'.9:  Vis. 13.4: SB 13:  187x and 250x they become a very tight pair, likely interacting.  Both galaxies have stellar cores, and are pretty small and faint.  One is oval and the other is round.

eg 6148:  0'.5 x 0'.3:  Vis. 16.1; SB 13.8:  This might be the most challenging NGC object to date.  Even using a very detailed pinpoint hand-drawn map, this galaxy is extremely difficult and elusive.  I had near-perfect transparency to aid me, finally catching glimpses of a very small, very dim oval immediately following the middle star of a faint trio.  It was glimpsed at 250x, 272x, and 375x.  NB:  Just as an aside, I was able to glimpse the central star in M 57 tonight, at 272x.  It was the best sighting yet with the 12"!
http://www.ngcicproject.org

eg 6149:  1'.1 x 0'.8:  Vis., SB 13.2:  Noted at 100x, it is bright but small.  At 136x it is small, oval, and very bright.  At 187x and 250x it is oval, has a very bright middle and has a fainter outer envelope.  It is a fairly elongated oval.
http://www.ngcicproject.org

eg 6168:  1'.4 x 0'.3:  Vis. 14.2; SB 13.1:  This galaxy appears as a long, very elusive slash.  It was spotted at 250x first, then viewed at 272x.  As full darkness was finally reached (June 27th/16) it was also seen at 187x, and then even at 136x.  A bright star is south (10.6 mag.).  Two very faint stars follow it.

eg 6181:  2'.5 x  1'.1:  Vis. 11.9; SB 12.5:  Viewed previously with the 8", and sketched at that time.  Tonight it was spotted at 60x, and viewed up to 272x.  It is large, very bright, and very elongated.  The central area seemed brighter, as if a bar ran through the length of the galaxy.  The edges are noticeably fainter.  Good views were had at 250x.  A rather impressive galaxy!

eg 6186:  1'.7 x 1'.3:  Vis. 12.9; SB 13.6:  Spotted at 100x, it is large, pretty bright, and oval.  136x shows a stellar core.  A very faint star is south.  It was also viewed at 250x, 272x, and 375x.  It is very oval, bright, and pretty large.  Fortunately it is far enough away from Beta to be seen well.
