VC200L. Fixed mirror. Tailored for imaging. Shame Vixen don't make a VC260L!  |
Great, wondered about the 200. So as an inexperienced frac boy, what's the pain points between fixed and not fixed mirror..slow optics would be a concern as well here.

The standard Vixen focuser holds a LOT of weight without shift - the same cannot be said for a LOT of Crayfords out there, especially most of the Chinese ones (mainland China or Taiwan). The Moonlites require a special locking mechanism (extra) if you don't really want slip.
Fit a Vixen dual speed knob to the standard focuser, and the world opens up - I use one continually. I swapped out the focuser (Moonlite) that came on my FL102S for the factory original, as I found it a LOT better.
My William Optics refractor focuser starts to slip with my SBIG camera with filter wheel. The Vixen does not even remotely.
The only downside to the VMC's is collimation - a real chore, but once you understand it and get it, it stays there.
Personally, I'd go the ZVixen due to the cheaper and more sensible adapters etc,compared to the buzzillion adaptors (at exorbitant prices) for the Taks.

Was hoping you would pipe up. Thanks for the update. Focuser and back plate is of big interest so experiences are valuable.
