Instrument: 18" Stabilite Newt f/4.2 1925mm fl

Filters used: none
Object: M81
Constellation: U. Major
Object data: Galaxy-Spiral
Size(s): 20x9'
Position: RA:09:56 DEC:+69:04
Magnitude: 6.9
Personal 'Rating' (at this aperture and sky condition): C+
The sky just wasn't dark enough to bring out the spiral arms
(see http://www.weatherman.com/edf.htm) Instead, a glowing 
central core, and an elliptal large area of nebulosity that
gradually faded into the light pollution. Two very prominent
foreground stars, and on the same side, and close double star
not far from the galaxy made the view intesting. Close up view
like this not as enjoyable as when viewed together with M82
with lower power and/or smaller rich field scopes.
thanks!
