I’m not sure whether this is an SGP issue or a Celestron Motor Focuser one. A couple of months ago something odd happened. The in-focus position was always about 21,000. Then one night when showing 21,000 the scope was completely out of focus with huge feint donuts.
The focuser has a full travel of 60,000. After a lot of attempting to find a focus point I tried a setting of 39,000 (60,000 - 21,000) and amazingly everything was in focus. For a while good focus has been around 39,000.
Two nights ago I selected an old sequence and the focuser position was reported as 21,000 but the scope was in focus.
I checked a recent sequence and it reported 39,000. Is the current position value saved with the sequence?
All the saved filter focus positions at the moment are around 39,000 so presumably would be useless.
Is there a way of resetting the reported position without actually moving the focuser or do I just have to delete the old sequences and recreate?
