One night I was testing my mount doing a No Meridian Flip imaging session. (Something Scott Losmandy mentions about the RAEXT)
As the mount came upon the warning beep, I reset the limit. I did that 3 times watching my telescope did not crash into my EX12 extension.
Finally, at 03:00 Hrs. I stopped as crashing was eminent.
So not only did I learn I don't have to do Meridian Flips anymore, I I also learned how to set limits on the fly, without disturbing my imaging run.
