M33 - Mixing old and new

Recommended Posts

With so little imaging time recently, I've been looking over some neglected data that I never got round to putting together. This is 2.5 hours of luminance and 100 min of Ha from last year, plus 2.5 hours of RGB from 2011 that I forgot I had.

Happily, they were finally united! (MN190 and QSI583 wsg).

Thanks, Francis.

You're right about the light pollution ..... plenty of nasty colour gradients to deal with on this one! And luminance subs were limited to only 150 sec at 1x1.

It still amazes me how modern CCDs seem to be able to punch right through even quite poor skies and deliver decent images.
