Okay, I think I figured this out. When I check the astrometry log, I found that it could solve the image using index file 4111. That means my FOV is too small when compare with the index files on my SM-OS. That means I have to change my lens to being the FOV to within the limits of my index files.
But I still could not understand why the log files are not being generated in KStars. Any help to solve this problem is much appreciated.
