Description

Hey there again,
Took a crack at M1 finally. Last time I did was over a year ago. J thought it would be a perfect place to to start a lesson on Messier objects on my Instagram page. The details in the remnant came out great, the black sky.... not so much. This was largely do to my lack of dithering. I've been using ASICAP for my acquisition, unfortunately it doesn't have a feature to auto dither. So unless I get up every 30 min and do it manually I get vertical streaks in my background. Any suggestion for a capture program that works for you guys?
