Combined 3.5h data on M31

[michael.h.f.wilkinson]

Just finished combining data from November 9 and 16, for a not so grand total of 3.5 hours minus a bit (all 60 s subs at ISO 800, with a modded EOS 550D). The extra data allowed me to be a bit more aggressive with curves.

Cropped version from Astro Pixel Processor

 

Curves applied in GIMP

Saturation enhanced a bit in GIMP

Background perhaps a bit too blue. Might want to fiddle with curves more tomorrow.

Nice image, which lense did you use?

I used my APM 80 mm F/6 triplet with Tele-Vue TRF2008 0.8x reducer
