First, I apologize for not asking my question clearly last time, so here goes a second try:
I see there is a new Pegasus product coming out soon, that is an OAG with a built in ASCOM motorized focuser of it’s own. This seems like a product I really want to use.
How can I use that new product with SGP / PHD2 ?
My understanding is that PHD2 makes its own exclusive connection to it’s guide camera, and since it does not have autofocus capability, there is an issue trying to use SGP’s autofocus for this new product in a sequence. Since SGP currently does not have the ability to connect and disconnect PHD during a sequence, the guide camera can not pass data to SGP for autofocus.
(The use case for this is that my filter wheel is not in my guide camera/OAG’s optical path (it is after the OAG), and thus any focus offset in my filters will cause my guide camera to go out of focus (after autofocusing the main camera). My main ASCOM focuser is between the telescope and the OAG.
There is significant focus difference between some of my filters, that cause the guide camera to be far enough out of focus to make guiding impossible. I realize that some believe that out of focus guiding is not harmful or even good, that may be true for minute out of focus conditions, but the offsets I have found with my filters, have proven to cause focus difference be to drastic enough to prevent decent guiding at all.
