Hi Roger, thanks for your comments. As you will be aware of the image shift with the LX scopes and from what I have experienced it gets worse with the larger diameters; I want to use my Feather Touch focuser with the focal reducer.

To use the F.R. as designed to screw onto the rear of the OTA and then in my case rely on standard focus, shifting the primary, with image shift is a quick way to get frustrated.

So I have screwed a 2" adapter onto the front of the FR, that will slide inside the Feather Touch focuser. Then I get focus on a bright star with the camera, lock the focuser and remove the camera; slide in a eyepiece and extention tube to find the DSO. The eyepiece is locked into the tube to be parfocal with the camera focus.

If I had GOTO, I most likely would not have to do all that to find the faint objects.
