Yes it does symlink for the first step. Also, do you know that Siril handles now the FITS compression. Very useful when not a lot of disk space
.
@lock042 Wow, that's great. Thanks for the hint. This is reducing the amount of diskspace needed for processing copies by more than a factor 5.
What I don't understand is the compression method and the quantization. Are the default parameters recommended on un calibrated images? The tool tip is saying that rice is having losses. But whats with the other methods?
I have some more questions, if you don't mind
When would I use the deconvolution tool in my workflow? With the predecessor tool I could never achieve any improvements therefore I never used it. And is there a description on how to use the parameters most efficiently?
I currently use to debayer my fits with RGGB in opposite direction but this is producing a mirrored image. The are some new offset parameters now. Can I somehow avoid this with the new parameters?
At the end, my only significant problem left in Siril is to produce colored stars over the full range of star colors up to middle of the star center. Red stars look pale orange after stretching, blue ones remain more or less white. I cannot achieve red and blue stars. I assume this is cause stretching makes stars burning out and become white at the center. I understood that asinh stretching is protecting the star colors. But I never can stretch with asinh far enough that blue stars remain blue in the center after the final stretch. It's because the asinh stretch is producing oversaturated color artifacts very quickly in my images. I apply asinh on the unstretched image right after background extraction and background neutralize and apply photometric color calibration on the stretched image right before removing green noise and saving the image for post processing. Is there a workflow to protect colors down to the star center even after the final stretch? I know that other software (like e.g. star tools) is achieving that by stretching luminance and color information separately. But how could I do something similar in Siril?
A smaller issue is to deal with aromatic aberration of the atmosphere. Currently I use a workaround to split the image into r, g, b and use the RGB composite tool to put it together again. The problem is that this has to be done before stretching because you get color artifacts if done afterwards. Tools like Fitswork and Autostakkert have a align color channel feature. Would it be an idea to add an option doing this automatically during stacking/registration?
Apart from that again a big thank you. The deeper I dive into all those new feature the more exited I become. There's still a lot to test for me like the new HA/OIII extraction for my duo band images I just found in the documentation.
