Notes: Moon was beginning to encroach in the west/southwest, so I am beginning monthly imaging in the northeast. This one came out better than expected ... Of the 67 subs I took, I was only able to use 52. A combination of poor seeing (5-6 second subs), and winds/breezes, caused poor tracking in declination. My 1940's technology mount is not very responsive to quick changes in direction, so I tossed 15 subs for tailing/seeing.

17.5" (3/1/03): at 380x this is a bright, very elongated galaxy with an unusual 
asymmetric appearance, situated less than 1' S of a mag 9.5 star!  Extended 
nearly 5:2 NW-SE, 2.0'x0.8'.  The bright core is offset to the NW side of the 
glow, with a tail extending SE, possibly bending at a slight angle to the core.  
Two stellar "nuclei" are visible in good seeing.  The brighter "star" is 
embedded with the core, possibly just slightly N of center.  A second fainter 
"star" is close SE, near the edge of the core and is visible intermittently.  
These stars are actually SSC's (luminous super-star clusters).

17.5" (1/12/02): very bright, elongated 5:2 WNW-ESE, 2.5'x1.1', high but 
irregular surface brightness with an asymmetric appearance.  The very bright 
core is mottled and irregular and is offset to the NW side of the galaxy!  At 
380x, there are two stellar "nuclei" within this glow.  The brighter stellar 
nucleus is fairly easy and a fainter stellar point is close SE.  There is also a 
strong impression of a third stellar spot close W of the central nucleus.  These 
faint "stars" are actually luminous super-star clusters, the most massive known 
type of star clusters (color image at  A mag 10 star is close off 
the N side, 1' from center and a mag 13 star is just off the SE end.  N1569 is 
probably a member of the Maffei 1 - IC 342 group.

13" (1/18/85): very bright, elongated 2:1 WNW-ESE, high surface brightness, 
elongated bright core, mottling suspected.  Located just 1' S of a mag 10 star.

8" (11/28/81): fairly bright, small, elongated.  Located just south of a mag 9
