1.25" T Adapter vs. SCT T Adapter new
      #5626705 - 01/16/13 06:07 PM

I currently have a Nexstar 8SE SCT scope and a Canon T3i. I want to take some solar system images and need to get the T Adapter. I wanted to know what is the better adapter, the SCT or generic 1.25". Each has it's own obvious advantages, but I want to know if there is a reason to get one over the other.

Definitely get the SCT adapter. You'll get a much more solid connection to the scope.

Just curious, what do you see as "obvious advantages" of the 1.25" adapter?

You can use the 1.25" adapter on any scope. you aren't limited to using it on a SCT. It's more future-proof if I ever get a Newt or Refractor.

Ah, I see. Personally though, I wouldn't use a DSLR on a 1.25" barrel connector. There's just not enough stability with that small of a tube, plus it limits the view and can cause vignetting.

Using a T-to-2" adapter gives a much more solid connection, although it does require a 2" diagonal or visual back (or focuser in the case of a different scope type). And the larger opening does not constrict the optical path.

I'd still go for the SCT connector as my first choice, but a 2" adapter would be ok too.
