I have a 2x TV Powermate that I've never used and wanting to place it in my image train for the Mars opposition but not certain on how to go about this...
I have a 9.25 EdgeHD and my backfocus is more or less perfect to my ASI533 at 146mm using the following:
C9.25 -> 0.7 Reducer -> Esatto Microfocuser -> Celestron OAG -> ASI 533
Is it best to put the PM in between the COAG and ASI533? I know that the PM is parfocal so that shouldn't affect my back focus but this would increase the distance from the prism to the imaging sensor so would I need to adjust the guide camera that same distance so both imaging and guide camera achieve focus? Or do I take the COAG out of the image train completely ?
If anyone has photos of their image train handy using a PM I would love to see them?
