For the Experts - Fastar...& C-Mount

Since Celestron's & Meades's SCT are similar scopes in design, how come meade's scopes are not Fastar compatible?
Is there an aftermarket fix for this?

And last question, what are the adapters required to get from a C-Mount CCD camera to 1.25" or especially 2.0 inch focuser? (my scope is an LX200).

Inquiring mind wants to know !

In advance, Thanks for your time and consideration in this matter.

Peter, I'm no expert by far, but having owned both, I do know a few things about them. Celestron's FASTAR tubes (not all are capbable) have a removable secondary. It is a specially designed front corrector plate and secondary to be able to remove it w/o tools. Meades just don't have the capablity to be removed easily. As for an aftermarket? I doubt it. It' be a very serious undertaking, although some enterprising person may attempt it someday. The last question I have no idea.

Here is a link to a site with the adapters you need:

I would consider using a SCT to T adapter along with a C to T mount adapter because all the connections would be secure so there would be less chance of dropping the CCD camera. You probably already have the SCT to T-thread adapter if you have done conventional astrophotography with a 35mm SLR.
The C to T mount adapter can also be ordered online for a few bucks more through Edmund Scientific here:
