I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.

Quote:In this case, there is no real fixing unless you're prepared to make a custom SCT corrector. You could retrofit the optics from a celestron into the OTA, though I don't know what purpose this would serve. Sort of like building a Gremlin on a Pinto chassis.-Rich
