OK, so here is my next (possibly silly!) question about OAG
Does the position of the prism affect the focus distance to the Camera being used for guiding?
I have the Atik kit, and I simply cannot reach focus with the guide camera. It has a fairly simple focus arrangement, but when I focus the main camera the guide cam will not be focussed when wound fully in, and the focus get worse as I wind out.
I did place the prism in a bit to try to maximise the amount of light it picks up. Could that be the reason I cannot get focus?
Cheers
Malcolm
