Default M101 in Ursa Major

All,

The past two new moon cycles I have been collecting color data and while
conditions could have been better this turned out better than I had hoped.


253mm RC @ f/9 AP900GTO, ST10-XME 8x600 seconds LRGB collected using
ACP/Maxim etc and processed using CCD-Stack. Assembled as a color
combine in Photoshop. Image scale of .62 arc sec/pixel.

Comments Welcomed


Regards

Bill
