I have a fastar assembly for a c8 that I wish to offer for trade. This makes your c8 an f/1.95 astrograph for lack of a better term. This was designed to be used with the st-237. However it works very well with starlight-xpress camera's as well. I am looking for a 27mm-35mm panoptic from televue or a nice crayford 2" focuser for the trade. If you have one lets talk!
