Re: [APML] Comet Machholz in Cassiopeia

Thanks Ray! Yes, that's why I said I'm not totally happy with it. It just doesn't have much punch, especially around the Double Cluster. Thanks for the tip. I'll work on it more soon.

Excellent framing, Gary. One of my favourite sky regions to shoot, with
or without a bright comet passing through!

I think you could stretch the contrast a bit more... There's scope to
darken the background a little without making it a clipped black. And
your brightest stars are not quite fully white - they're rather bright
grey - so I suspect they were already clipped at the bright end before
you subtracted the gradient? If you fixed that, it would make the final
image really sparkle.
