I'm considering purchasing the STF 8300M package with the FW5 and the OAG. My question is this: I would like to use my ZWO 1120 as the guide camera but not sure of the clearance of the OAG from the filterwheel case. Just a rough measurement of the ZWO shows approx. 1/2" from the outer edge of the tube to the outside of the camera case. Can anyone answer that question. I'm already looking at $4k plus here and I'd just as well not have to buy the ST-I if I don't have to. Thanks for your help...
The OAG goes together in four different orientations, and can be mounted in four different orientations. You should be able to mount it such that it does not interact with the camera. A quick read of the drawings suggests 0.7" clearance in any case.
