Initial (limits) setup?
Posted: Tue Apr 20, 2021 9:20 am
Hello there. I’m installing the FC2 on a Celestron SCT. The physical installation went very easily, but I’m curious what I need to do to set initial limits. This is a new telescope for me, and I am new to electronic focusing.
Is there a documented process for setting in/out limits so I don’t accidentally cause damage? A calibration process?
I understand the focus controller application has the ability to set limits, what I am looking for is the proper way to identify those limits for my scope. For instance, the Celestron electronic focuser has a calibration process where it runs the focus in/out and automatically determines the limits and sets the max to be prior to those limits. I assume I'll be conducting a similar process (albeit manually possibly) but I am just not sure the best way to go about it. What happens if the the focuser hits a mechanical limit? Does the motor sense that and prevent further travel in that direction?
I can’t see to find anything on this.
Thanks.
