In KStars 2.9.3, I worked on initial integration of
SEP
. You can think of SEP as a Sextractor Library. So the primary purpose of SEP in KStars is to aid with photometry work that I yet have to start in the future, but it has other purposes as well. In v2.9.3, you can select SEP as one of the detection algorithms in the focus module.
I'd like to get feedback on that. How reliable is SEP in detecting stars? is the red circle accurate?
My roll-away should be...rolling beginning of April, so for sure I'll be giving this a try. I hope it will properly recognize galaxy cores as what they are
Finally, after spring break (kids), work travel, and terrible weather I got a clear night and a bit of time. I did some basic testing of SEP in the focus module that comprised of running the focus module both with the default of gradient detection and SEP. Gradient worked and selected a star. SEP did not. Instead it either found a hot pixel or a blank area and the focus module continued with attempting to focus. Obviously it failed.
Looking at the red circles in the focus module I see that SEP does find a couple of stars but also hot pixels.

Right, I already found issues with SEP and fixed them in KStars GIT. I will use your frames to see if it still holds, thanks for providing the frames that's a tremendous help!!
