I am trying out various software. This is a re-process of NGC281 which I imaged December 2020 - my scope was very poorly at the time and there is a very distinct tilt/gradient (in particular the bowl of frog spawn which is the top left corner). There are some very splodgy stars and, probably, the colour is too saturated.
My reworking is:

My original was:

On balance, I think that I have done a slightly better job this time. At least, my stars have some colour.
Oh for a dark, clear sky that lasts long enough to make it worthwhile setting up. Perhaps I should take up underwater astrophotography.

Hi John,
The reworking is a much nicer crop. I think you may have stretched it too far. Data looks bifurcated.
Clear Skies.

Thanks, I do need to keep my enthusiasm in check!!!
