Re: Colour Mottling / Background Noise (M31)

Hi, just for security reasons: 1.6sec sub exposure time seems to be quite short, even at ISO 1600 (you did not mention what lens?); did you check the histogram of a single sub? The sky background should be bright enough - some people say the peak of the histogram should be at about 25% from the left...

Re: pale/missing colours in dark areas

Re: pale/missing colours in dark areas

Hi Ivo, I checked the settings in DSS - and of course - you are right. I failed to set "No White Balance Processing" in the RAW File Settings and therefore the dataset already was balanced. Shame over me. For sure, I read the "Recommended Deep Sky Stacker settings" several times - no idea what went ...

Re: pale/missing colours in dark areas

Hi Jochen, thanks for your reply! I already pushed Dark Saturation to "Full", but it effected only slightly brighter areas, not the dark areas shown in the cutouts. Concerning the other mentioned parameters: - I already tried the matrix correction, but my camera model EOS 2000D is not listed. I trie...

Re: pale/missing colours in dark areas

Hi Ivo, thanks a lot. At first I will double ckeck the settings for colour balancing in DSS. This would mean, that a lot of or at least some my other images have been wrongly stacked as well :roll: .

pale/missing colours in dark areas

Hi there! I am currently reprocessing an image I took some years ago - now with StarTools, which I discovered in the meantime. This is really a stunning piece of software :bow-yellow: , and I would like to take advantage of the great and advanced possibilities. Now I am facing the problem of missing...
