First time processing with PixInsight! The stacked image had some gradient issues that I couldn't ignore, so I realized it was time for better software. GIMP and Paint.NET served me well in the past, but I've been missing out on a lot.
The ES80 is still pretty new to me. I have noticed that being slightly out of focus (in only one direction) results in purple halos, which are visible here. Is this normal? I could probably benefit from a Bahtinov mask.
125 minutes of integration. More details on Flickr.
