Failed Platesolve during AutoCenter

Sequence Generator Plate Solving
1

Description

I use auto centering when slewing to a target. I have Pinpoint set up as my plate solver.

I have a successful plate solve on the initial slew. There is an offset error detected. The telescope is moved. Then the next plate solve fails. It goes to blind solver and then solves successfully, and then I am off and running.

When I look at the log file, and compare the first and second plate solve outputs, it shows this:

Don’t know why all the data is missing in the second plate solve which then causes the fail.

Log attached.

Thanks,

If you are able to reproduce this behavior, it would be helpful to save off the frame used for the failed plate solve (right click, save to disk). Then, sometime during the day or whenever you have time, close and re-open SGPro. Open the FITS file you saved off, then right-click -> plate solve. Enter the same hints as cited in the logs and see what happens. Then, if that works, right-click and plate solve again to see if the subsequent solve works. Having answers here will make hunting for this issue a bit easier.
