Another of those objects that I image as the moon is becoming full ... this one had a tough background to process ... presenting the background a little darker than I would like.

17.5" (7/22/01): fairly bright, fairly large, elongated 2:1 NW-SE, ~2.5'x1.5', 
small bright core.  Contains a bright stellar nucleus or a star is superimposed 
at the center of the core.  A ver faint star is just off the NW edge.  At the NW 
end a faint spiral arm is attached to the main body, winding north and then 
trailing back nearly halfway along the NE flank (this increases the dimensions 
to ~2.5'x2.0').  With concentration a dark gap is visible between the arm and 
the main body (bar) of the galaxy.  A very short extension is strongly suggested 
at the SE end, bending towards the west.  All of these features were sketched 
and later verified on the DSS.

17.5": fairly bright, bright stellar nucleus, elongated.  Irregular appearance; 
either darker or an indentation on one side.

13": fairly bright, slightly elongated, stellar nucleus, fairly diffuse outer 
halo.

8": faint, fairly small, slightly elongated.
