Celestron OAG question
Is anyone on IIS using the Celestron OAG, specifically on a C925 with the Celestron reducer/corrector?
Having finally lashed out and bought a guide cam in the continuing slow build up of parts for AP. I am seriously looking at setting it up on an OAG as image shift is noticeable when focusing these scopes. I have to assume that the mirror is likely to move somewhat under gravity as well as the scope moves through the night and through an OAG at least the impact would be reduced by the guider, where a guidescope will sit there fat dumb and happy.
Just wondering about the reducer as the Celestron manual for the OAG does not mention it. I assume that the reducer goes in front of the OAG and then some fiddling with spacers may be required to get the sensor (DSLR) at the right distance from the reducer?
