Hello, I have an ST2000XM with the CFW8 permanently mounted to the camera. I'm trying to use a TS OAG9 as an offaxis guider in front of the filter wheel (which gives me almost exactly 55mm to the focal plane) but two of the small button head screws that hold the front plate onto the CFW8 just foul the body of the OAG. Rather than running with only 4 screws, I was thinking of drilling and tapping a couple of extra holes of the same diameter in the wall of the CFW8 body - does anyone know what the thread size is for those screws at all? Many thanks Graeme
(Sorry - this should have gone into the Filter Wheel section - if it can be moved that would be great!)
