Thank you Scott, that's an interesting review. I do find fairly regular bake-offs for terrestrial photos. I'm convinced though that doing astro well requires some different skills. What surprised me was that WHCC and ArtBeat had similar quality (i…

Yes, done that for years with terrestrial photography, while soft proofing is the "right" way, I find it much more effective to get a small print of a typical photo, view it in light it would normally be in, and have it next to my monitor and adjust…

Thank you. I'll give it a try. I was worried about a hard edge on the mask, but (sound of hand slapping forehead) I can just feather it with a convolution before applying the mask.

I spent several days and lots of experimentation with this, and with no theory to back it up but one data point here is what I found. It was easier to get a balanced result (in terms of different channels) but doing the HDRMST process on each channe…

Ah, well, "yes" or "no" are simple. It's the justification is complex. :) I will be very interested if you get data and have an answer. If you have any interest in ASI6200MM data I'd be happy to oblige (transfer logistics to be worked out, they…

Well, I guess it's time to change. Thank you both for the advice.

Interesting, and thank you. So you do, indeed, keep originals of every single thing, as Juan recommended.

Thank you I will try.

Sorry for delay, I thought I would get notified of responses, but didn't.... The latest reason for this is to replace the NB stars with RGB stars, but substantially reduced RGB stars as well. Where the RGB stars are large that works, but if I tune…
