I’ve been using Siril for a few months to process photos from my Seestar. Siril is really good but I have a few requests to make it better (in approx. order of priority).
For stretching in GHS, I’d like a “Preview” option (or maybe just a “show previous” while holding a button) to see the effect of a stretch option. This would be much better than accepting the stretch, then checking “undo” & “redo”. Likewise in the Background Stretch under Star Recomposition.
I suggest the “Ready” indication and the progress bar be much brighter so they show up better.
I’ve used the trick in Deep Space Astro “Create a Pseudo Mask in Siril”, https://www.youtube.com/watch?v=R7j0foGXBaQ
to adjust luminance of part of an image while protecting bright objects. It would help to be able to better do this with a bright elliptical object. (For example, brightening the Horsehead without blowing our Alnitak). I would like an elliptical (or stretchable round) selection in addition to the existing rectangular selection. A true mask as in Photoshop would be even better.
It would be helpful to have a better indication for when some processing options, such as Photometric Color Calibration, have concluded. Perhaps just dim the “OK” button when the task is finished.
In star removal, allow a preference to default to “Pre-stretch linear image”.
Thanks for truly useful software,
Fred
