Messed up autostretch in Siril after GraXpert treatment - Forums

Hello,

As the title says,after using GraXpert (gradient AI and denoise AI) on a fresh stack and when I open the saved file on Siril again, the autostretch view is totally messed up.

The autostretch view is way too much streched, it actually looks like Histogram view… It's not a big issue because when I do a manual stech the image is OK but it's kind of complicated for the steps that must be done before the stretch…

Any idea?

Thanks

I Would do this:

After stack - Auto strech - background extracktion - extracktion again if needed - back to liniær mode - Histogram Transformation and push apply auto strech algoritme - apply histogram transformation - and final ….save as 16 bit TIFF.. even if it is mono or color.
Hopes thats help.

Did you save the processed or stretched and processed? Also, was it saved as tiff or fit? I have noticed this as well but it can be fixed by how it is saved. I have started using Graxpert for the starless stretch and it does a really nice job for me. After you fully process your image you can convert it to something close to SHO by opening it back up in Graxpert then give it a 10% stretch and unlink the channels and it will give you an entirely different looking image, close to SHO with multiple colors. See my short youtube video on it. https://m.youtube.com/i’m sure i saved processed only, about the format I will check.
just saw your video I’ll try tomorrow !
