#108 Hercules NGC Project Part 2: Uranometria Chart 86

Only a few NGC galaxies appear on Chart 86, so this will be a short entry.  A few of the galaxies also appear on other charts.  NGC 6347, for example, has already been discussed on the page with Chart 87 (see Part 1).

CHART 86

eg 6375:  1'.6 x 1'.6:  Vis. 13.9; SB 14.9:  I expected trouble here, but I located the galaxy quite easily at 100x.  Transparency was excellent at the time.  It was also observed at 136x and 187x, being large, round, and showing a stellar core.  At 187x I noted a very faint star immediately north following.

eg 6379:  1'.1 x 1':  Vis. 12.9; SB 12.8:  It was spotted at 100x and observed well thru 250x.  It is quite faint, and it follows a bright star.  It was round and seen best with averted vision, though it was easy to see.  However, no detail could be discerned.

eg 6389:  2'.8 x 1'.9:  Vis. 12.1; SB 13.7:  One of the largest and brightest galaxies in Hercules.  Spotted easily at 60x, it was large, bright, and oval.  Views were quite nice at 100x and 136x, showing a stellar core, bright central globe, and fainter haze all around.  At 187x and 250x it is still bright and very large.  Recommended viewing.

eg 6574:  1'.4 x 1'.1:  Vis. 12; SB 12.3:  Viewed at 60x, and very bright at 110x and 136x.  It sits at the north end of a faint star stream.  It has a very bright center, and it is very oval.  At 187x a faint star is seen just south (mag. 14?).  250x shows a very bright stellar core.  Viewed years ago with an 8".

eg 6627:  1'.3 x 1'.1:  Vis. 13.3; SB 13.5:  Spotted at 100x, it was small but pretty bright.  At 136x and 187x it was a bit easier to view.  It appears slightly oval in this range.

eg 6635:  1' x 0'.9:  Vis. 13.4; SB 13.1:  Only suspected at 100x, the galaxy was confirmed at 136x.  At 187x it is small, oval, but pretty bright.  At 250x it becomes ghostly.  It is immediately north of a bright star (mag. 11?), which helps to hide it.

NOTE:  eg 6467 and eg 6555 are discussed elsewhere, Charts 68 and 67 respectively.
