Incredible ! How could you tell ?
Yes, this image is with a 200mm canon lens, and unguided. I also used drift alignment only on the RA axis. And I dithered manually, and perhaps a bit too much, in order to eliminate banding
When I only use 10 frames or so, BPP performs extremely well and without the banding !
Last night I read a thread that one does not have to expect PI to make an incredible image out of " crappy" data. Mea Culpa !
But since DSS can handle these images, I suppose I could tweak some parameters here and there to make the best out of my stack ?
I tried to use Linear fit instead of winsorized sigma and change the sliders a little bit. At first that seemed to work but then again it failed.
Is there a way to score my images ? So I can only use the best ones ?
Next time I will try to produce a better stack by guiding and aligning.
