Abort image causes SGP to lock up... disastor ensues

Sequence Generator Equipment Compatibility

Last night I was running a sequence and everything was going fine.

Somewhere around 12:30am an imaged failed to download in the allotted time and SGP sent an abort command to the camera and SGP froze up. Well it did not freeze up per se, it continued to ‘try’ to issue commands but there were no responses. PHD kept running and the mount kept tracking until sometime that night it finally struck the pier and nearly ripped the usb cable out of the filter wheel. I am very lucky in that was all the damage done apparently. The CGX-L is a ‘powerful’ mount and surprised it did not rip the camera and wheel off the OTA.

I have witnessed this behavior before when running frame and focus routine ‘looping’ and sent a stop command. The camera never responds and SGP locks up requiring a power cycle to the camera and SGP to be closed and re-started.

The particulars: Mount: Celestron CGX-L, Camera Atik383L+, Filter wheel Atik EFW2, Guide camera: Loadstar X2, PHD2 ver 2.63, SGP version 2.6.023

Here is a link to the log file

Many thanks!

Without such nearly dire consequences this has happened to me too.

Well at least I am not alone. Same camera?

Putting the SGP lockup to one side, is there no independent method to stop tracking on the mount to avoid crashes? It usually is in the handset or driver…

There is of course RA slew limits which I had set previously.

However recently I had to re-set the hand controller to factory defaults for a reason and I had forgot to set those limits again.

However SGP ‘should’ have intervened and sent the mount to its park position, warmed the camera, and shut everything off. Which it did not do any of.
