Description

I'm horrible at processing galaxies, but since it's galaxy season, I thought I'd try M 101.  This is 16h 30m of total exposure time:
39 Blue @300s
40 Green @300s
40 Red @300s
74 Luminance @300s
7 H-alpha @300s (I had a lot more but I left my Bahtinov Mask on)
I took this over about 4 nights with my NP127is / ASI 6200MM at about Bortle 4.5.  I was also, simultaneously, imaging with my TV-85 / QHY 268M, but I haven't finished processing that data.  So when I get that data processed I'm going to combine the two sets and have a 33h image.
BTW, this is REALLY cropped, cause with the huge sensor on the 6200 the galaxy is about the size of a half dollar on a 27" monitor!
Anyway, hope ya like this one, so far!
Tom
