Scops OAG connection

Hi Guys
Does anyone know if the Pegasus Astro OAG connects to SGP so you can control the off sets of the guider to matach the filter used so the guide star says in focus? I see it has stand-alone software for this but can it sync with SGP
Cheers

Not at the moment. Are you finding that your OAG and Imaging Camera are substantially out of focus after a filter change? I have a Sagitta (same idea as the Scops) and haven’t found it necessary to adjust the focus of the OAG per filter.

Thanks Jared

Yes I have a MOAG and zwo asi2600mm
On a 16 inch scope.I was worried about square stars at first and then I noticed guide scope went out of focus after filter change have I got the numbers wrong?.
So I was thinking if I can change the focus remotely would be good
Any thoughts would be great
Cheers

Any way of getting the pick off prism in front of the filters?

If the filters are different thickness, a change from a thin filter to a thicker filter will cause the backfocus to the imaging camera to change and thus also require a cooresponding adjustment in n the OAG guide camera focus. I found out the hard way by mixing 1mm filters with 3mm filters. This is with a drive train sequence: Flattener->OAG->FW->Image Camera.
