M82 is particularly good in suburban skies because of it's 
high surface brightness. It is further enhanced over smaller 
scopes by being able to show the dark lanes clearly at higher 
power with less straining. 
M82 is a streak of light cigar-shaped, roughly 10 arc 
minutes long. It is very complex looking but one can 
definitely make out three distinct dark lanes criss-crossing 
the galaxy at 45 degree angles, slicing it up into roughly 
4 parts... somewhat triangular in shape. 
Needless to say, at low power, the object is framed 
beautifully with M81, a spiral galaxy of roughly equal 
size (but much fatter)
