Description

While I've been concentrating on this target with my NP127is / ASI 6200MM, I was simultaneously taking data with my TV85 / QHY 16200A with a 480mm fl at f/5.6, mostly in H-alpha.  I was playing with this data and came up with this wide field image.  I need to reshoot my flats cause there's flat fielding errors in the corners, but I didn't want to crop those out so as not to cut out the curtains of nebulosity at the top of the frame.  This is 60 subs @600s with an old Baader H-alpha filter.
Anyway, hope ya like it!
Tom
