Description: Words always fail me when describing the Great Galaxy!
I have not seen it in a large-aperture scope since I was a teenager,
and doing so in this dark sky was a treat! The central core of the
galaxy (maybe 45" dia?) was clearly distinguishable, as was a wider
elongated concentration of about 10'x5'. A dust arc just 5' S of
this central concentration was also glimpsed. A broad spiral dust
lane N of the center extended 45' E and 20' N, exhibiting obvious
(and beautiful)curvature. Another, inner spiral dust lane S of the
center, extending about 20' N-S, was also glimpsed. I can't wait to
see this object in dark skies once it's at higher elevation! NOTE:
Higher powers, especially 170x, were necessary for seeing some of
this detail! There's no lack of light from M31, so magnify it!
