Thanks Ivo.

Supporting all stackers and what they do to the headers is going to be impossible, but hopefully there are a few quick wins available

Yes, I'm sure it's going to be different for each stacking appllication.

Maybe take LIVETIME if it's set, and if not use EXPTIME

The auto-detection of the exposure time of images loaded in Compose is a great idea, but it doesn't work for files produced by Siril (via SirilIC if that makes any difference). It looks like siril is writing two different header values and ST picks the wrong one. EXPTIME is the individual exposure t...

Mike, this is my attempt at a straight "L, RGB" image from yesterday before you had posted your much more detailed attempt EagleNebula-Forum.jpg There was no attempt here to deal with the grey stars, but I did try to blend out the odd coloured artifacts the way you did on the RGB image. There's obvi...

OK, that's a bit better. Following Mike's suggested steps results in this: mikeCrop.jpg At least I know that it's an optical problem and that I can process my way around it if I have to. I expect it was a little cloudy, I'll check the optics when I can. As a full image I get this mike.jpg Not too ba...

Mike Thank you for all of your input, it's very helpful having someone else looking at the problems. I'll try your suggested settings for the workflow and see what it looks like. I have usually been trying Ha as L but just to have a look at the colour I'll do what you did and just use the RGB. I tak...

I'm still stumpted with this! This example is not a great data set, it wasn't possible to get much time on it, but I see artifacts like this in practically all of my images and I'd like to get to the bottom of what's going on. It may just be that the focus is different between channels (the scope is...

Yes there was a second autodev after wipe on both versions composed in ST. The version that was composed in ASTAP wasn't wiped, as even though I have turned all the cosmetic options off in ASTAP it still seems to be messing with the background of the image, and attempting to wipe it just made it wor...

Stacking seems to be playing a role here. My original image, and the way I usually stack images is done in Siril using SirilIC to drive it. As an experiment I tried using ASTAP for stacking and got the following using the default settings - A colour image composited by ASTAP and only displayed using...

No, but then this is from a mono camera, each filter on it's own looks OK The problem seems to appear in the colour module, up until then with the image only showing luminance, it looks fine. I'm fairly sure that the coloured highlights are an optical problem, the red frames are sharper than the gre...
