And this is prompt:

MY mount is ioptron CEM60,set:Stop at designated position, 1 degrees past meridian.
I am using iOptron Commander and ASCOM driver 5.0.1.2 beta (this version was fixed the meridian flip bug with SGP)

My SGPro program(v2.4.3.23) has this bug also:

I kindly suggest that we could not use a modal message box in fully automatic astro photography control software , this will require human intervention.

There is the log file:

@tianbin Please do not include snippets or partial logs. If you can upload the full log plus the logs for your ASCOM mount we can help you troubleshoot.

Agreed. This error will now auto-expire in 30 seconds, send a notification and then abort the sequence (without human intervention).

@tianbin Are you using the “Wait for meridian” options? It seems like you might be and we might have a bug there (for your particular kind of scope).

@Ken Yes, I used “Wait for meridian”,and “Mount settling time: 1 sec”.

OK. Thanks. I think I have this issue resolved then. It only affects users of scopes that do not support pier side flipping and use the “Wait for meridian” option. It will be available in 2.5.0.17.
