Last night, I had a failed meridian flip. On further investigation, it turns out that SGPro didn’t provide any hints to Pinpoint and as a result, the plate solve (and meridian flip failed). I checked the plate solve image and sure enough, there aren’t any of the hints (RA, DEC, scale…) in it.
Furthermore on this fail, SGPro did not attempt to blind solve the image (which would have succeeded).
I have my log file here: https://drive.google.com/open?id=0B0KcEqw-v71VaWtaQkVqV2loUUk (at 3:12, SGPro attempts the Meridian Flip and you can see that no hints are written to the image)
The plate solve image is here: https://drive.google.com/open?id=0B0KcEqw-v71VMkFVVEdFSl9kcTA
The night before it still worked and the only thing I changed in the Control Panel is the temperature compensation step size.
Any ideas are appreciated!
