I have an LX200GPS with a Meade Electric Focuser, Eyeopener, and F6.3 Focal reducer with a QHY8 Camera. Currently I have been using the focal reducer after the electric focuser just before the camera. I did not have the adaptor to connect the focal reducer at the visual back of the scope.

That has now changed and I am able to move the focal reducer back to the visual back of the scope. However before I do,, I would like to ask what is the best? An I correct in thinking that the further back I place the reducer the more I will increase the F:stop, hence reducing my field of view. I know I cn do some trial and error, but would like to ask the question to make sure I understand the process. I have read that moving the focal reducer back away from the visual back effects (increase) the F:ratio


Thanks
