Edited this - as I realise to manage the optical train link I need a combination OAG + flip mirror and wonder if anyone has experience / views on this?
Models I have found so far are the Taurus Tracker3 and the Van Slyke Slider 2.
Basically what I want to do is have a way of flipping my main imaging scope (a C9.25) from an astrophotography set up to visual work and back with just a flip of a switch. As all my eye-pieces (Vixen LWVs are parfocal) and all these sorts of combination devices have precise focusers on both the pick off prism and the flip mirror eye-piece - I should be able to precisely focus all elements of the image train.
Interested in folks thoughts!
