Description

Unfortunately i somehow dont get good results when using flat frames in DSS. This is why i tried to remove the vignetting and colorcast in Photoshop which killed some of the dust clowds.
Upon close inspection you can clearly see the coma caused by the newtonian.
Edit: One thing i didn`t like about the old image version was the strong vignette which i failed to remove due to faulty flats. I heard alot of good things about Pixinsight and i`m currently trying out the trial version. The DBE tool allowed to remove the vignette. I think it did a pretty good job. I think i will buy this software on the long run as it does have tons of functions which seem quite mighty and are not easily reproducable in Photoshop.
