Looks good. If you have any other problem send me a message. Feedback helps. cs, Han

Detected image stars are red annotated and database star used are yellow annotated

The image solves if you reduce the maximum number of stars to 20. Look to the first screenshot with downsampling 0 (auto) equals 1 for the dimensions. So star are not detected due the distortion. When forcing binning to 2 much more stars are used since they look rounder due to the binning. So the main problem is the star shape. You could fix it by forcing binning 2 and reduce the max number of stars to use to 20. But this will produce a permanent warning. Probably a dark will also help. I do not...

Hi Andre, Zero values are ignored but any other value will be used in the first background calculation. So it will initially using the wrong background value . This is normally the most common value. However when not enough star are detected it will try some other methods and finally divide the image in many sections and calculate individual background values. So it will detect the stars. The field-of-view is pretty small making it more difficult to find a match. More later. cs, Han

It is now fixed in the GTK3 version. cs, Han
