Very nice Jack, it looks like I really have something to look forward to! Alot more evenly illuminated and fringing isnt nearly as bad. My strange color shift is because of the color of the skyglow filter. I think I will try M33 tonight without a filter and see what happens. ALTHOUGH, without the filter, my max exposure is about 7 to 14 seconds in my light poluted location. I live in a red/orange border zone.
