The 2" TCF-Si is $645USD plus the cost of the adapter for your scope which is below $100US..
Its cheaper than a 2" FT with the FT digital focus system and the telescope adapter.. Although more expensive than the moonlite with stepper motor... The TCF-Si would be better than the moonlite I think, going on the specifications in the literature alone... Continious temperature compensation would be nice thats for sure.. although Fred tells me calibrating it can be a right pain in the butt...
