Galaxy NGC 7331

[Roy Foreman]

Yet another image grabbed through a gap in the clouds, so once again not enough data for a really clean image, but it is my best image of this galaxy to date.

16" F/4.5 Reflector

ZWO ASI 6200 Mc Pro

UV-IR Cut Filter

30 x 60 sec at gain 360

Processed in DSS and PS

Great result from 30mins exposure.  Good that you had that big scope.

I thought it looked a tad green so ran it through HLVG in PS.  Hope you don't mind me uploading for comparison

Thanks Martin - yes a definite improvement.  I recently calibrated my screen, but I'm not sure it has improved the colour balance. Seems I will need to redo it.

Yes only 30 mins capture time. When my skies are clear they are dark enough to image without filters, but these days they never seem to stay dark enough for long enough to capture enough data. Having a 16" scope definitely helps !
