M101 in a hurry.
Photo description / processing
A test and not very successful outing. The entire imaging setup was assembled hastily in the dark with a flashlight, polar alignment was done by eye through the finder, and the guide scope fogged up — all frames have slight blur. There was only a little over an hour left until dawn, so only 50 minutes of exposure were captured. Lights and darks were taken.
