This galaxy (pair?) is relatively easy to find.  There appeared to be two 
components.  One was shaped somewhat like a boomerang, bright on the northwest 
end and gradually fading into the background sky glow on the southeast end.  The
convex side of the bend was to the southwest.  A faint, wedge shaped area of 
nebulosity was located adjacent to and south of this fainter end with a dark 
lane running in between.  At times the center of the bright section seamed to 
be stellar.  I neglected to write down which way north was when making the 
drawing.  I have based my directions in this description on the dss image.  A
