These do ya?

I've just taken delivery of a t-mount and adapter for my explorer 200p ds and I think I should have ordered one of these as well seeing as so many people ask about them for such scopes. Bah! :-)

You're going the wrong way, surely?

With a reflector you need to get closer to the secondary, not further away from it.

Or have I misunderstood?

Also, why use 1.25"? Surely your telescope has a 2" drawtube?

Connecting a DSLR via 1.25" will cause some serious vignetting in your images. The MaxDSLR adapter is the best bet for hooking up your camera (if you are indeed using a newtonian), and you wont need a T-Ring either.
