Dunk, Paul,
I know I am pushing this BUT I intend to use this setup in 2 modes, with an SLR and 50mm or 150mm F2.8 prime lens unguided for widefield AP when traveling.
2nd mode is the one I am talking about, a scope for AP/visual use at home or at dark sites that is better than my current WO 66 SD (which the mount can handle).
I am not a novice at this, my last setup was a 10" GSO RC on a G11 with an SBIG 2000xm ccd but I sold that when sent overseas. That gear was fantastic but is too heavy for my current purposes.
On further thought it seems to me the SpaceCat really is not really a candidate - it is not a visual scope (I think a visual back is available but really not much use I think??) it has been reported as having focus/tilt issues and even some optics issues, it is smaller than the 66 I already have etc etc and finally my Olympus PRO lenses are probably as good/better. The only plus is the true APO/FF nature of the scope (the Star 71 shares the same design).
A WO Star 71 seems to fit the bill well, it and the Stellarvue CF are both about 2.5 Kg and the imaging train I have in mind is about another 1.5 Kg. The Stellarvue requires a flattener etc so pushes the limit, so the WO is my first choice for now.
My plan is when using the scope for AP tracking will be enabled to compensate for the longer FL of the scope, if I use OSC with the SX AO option then the lack of dec correction is also fixed...
