Hi @garycphoto,

So I'm taking a look at the moment. I think there are some issues in your imagetrain. If you look at the masterbias and masterdark, I think you have light leaking on the sensor. This will interfere with proper calibration and will influence the result;

Besides that, you're using tif files which are already stretched. This will also not work regarding extracting Ha etc. You need unprocessed, raw data which is still linear.

@vincent-mod Thank you for the reply Vincent. I did send the files to another user and he could get the mono extractions from the ha and oiii.

Ah, yes so was that with these tif files or the sony raw files? At least it's not working here either indeed.

@vincent-modit was the raws. I can load raws into APP? Also thank you for bringing up the light leak in my calibration frames. I can close the viewfinder window on the back of my camera.

@garycphoto Yes, in general you can load RAWs in APP, depending on the camera used. If your friend was able to split the channels then APP supports your camera.

@vincent-mod It worked. The raws were the key. Now I can get the Hubble palette. Thank you so much!

Excellent. It's important in APP to keep the data linear all the way through, only when completely done with processing can you save the result as a stretched file. Having the raws now, allows for good calibration as well.
