In KStars 2.9.3, I worked on initial integration of
. 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?
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.
