Hi Bob
Sometimes tracking stops during the last image before meridian flip; the trailed image cannot be solved so after flip there is no pointing correction (except for the initial auto-center).
Details: Exptime 15s, no filter change. Flip settings - mount can track 10m past, needs 2m assurance. Log: entry says waiting 117 sec to pass flip limit (that log entry is after the trailed image is downloaded). Equipment, A-P 1200 GTO.
This failure happens only sometimes, even with the same 15s exptime.
Solution would be appreciated! Thanks.
