Description

Ole Alexander Ødegård has kindly allowed me to work on his excellent data on M101 and I have striven to bring out as much dust and detail as possible. Ole says he has limited time for processing, which is great for me since I like processing.

Equipment: TS 12" Imaging Newtonean (f/4) on a 10 Micron GM2000 HPSII, Canon 6D (modded), 22x300" (1.8 h) ISO 1600. April 10th 2016.

And, yes, I did remove the star spikes as I am no big fan of artifacts (but Ole Alexander is not 100% on my side there)
