|Hickson 69: Galaxy Cluster (Bootes) RA: 13h 55.5m / DEC: +25° 04'.4|
Instrument: 18-inch Obsession
Of the nine galaxies in the sketch at left, only one is a member of this compact galaxy cluster. The drawing represents a 141X view in my 18-inch Dobsonian. Near the center of the field, lies 15.7(B) magnitude PGC 49502. This 1'.2 by 0'.4 oval is Hickson 69A. It is skewed northeast to southwest at the apex of a triangular arrangement of 14th and 15th magnitude stars. It's not even the brightest galaxy in the field. About 4' to the southwest, 14.9 magnitude IC 4345 stands out as a 0'.9 by 0'.5 oval. This elliptical galaxy features a stellar core. Fain, tiny IC 4344 emerges as a 0'.7 by 0'.2 misty patch about 1'.5 south of IC 4345. It's a 15.5(P) magnitude barred spiral galaxy with a 12th magnitude GSC star smoldering 1' to the west. Sweeping about 6' northwest of IC 4345, the 15.6(P) magnitude glow of IC 4343 is teased from the night. Its appearance is plain; a 0'.2 diameter patch.
