Until recently, PlateSolve2 tended to always work, and worked quickly. A week ago or so, I began using my coma corrector, and accordingly reset the image scale. However, since this change I’ve never been able to get a successful PlateSolve2 solution, meaning I can’t sync, can’t center, and can’t do successful meridian flips. I thought perhaps I was getting a lot of hot pixels registered as stars so I played with the settings to eliminate that problem and viewing the image suggests I’m only using real stars; still no luck. So tonight between 6 and 7 PM I did a few experiments with plate solving on a 600-sec integrated image. PlateSolve2 either fails (usually) or gives an incorrect solution (occasionally), although the astrometry.net blind failover is working so I know my starting coordinates and image scale are not bad. I must be doing something stupid, but at this point I’m stuck and thought I’d best ask for help. I haven’t done the obvious test of removing the coma corrector to see if things still work without it, because solving really ought to work even with the slight scale change. My starting parameters and settings are attached, and my logfile and the image I’m using for testing are at this Dropbox link: https://www.dropbox.com/sh/hd8xmx0ddzpzv8k/AACPzwX-yXqCnL6ubCsMrXxQa?dl=0
Thanks in advance for any help!
