Description

Ha was only 60" because I wasn't autoguiding. I'm amazed it worked as well as it did, even at F4.8.

I see I need to go back and reprocess, to remove the ringing.

__________________________________________________________________________________

New version removes almost all the ringing. The nebula is a tad softer, the stars way better. Tradeoffs.

I think the purple cast is real, H beta. I ColorFit the RGB.

I find "reality" a slippery concept, particularly re color. There's a lot of subjectivity involved. I now find the original way too orange, that can't be correct.
