Which Powermate?

[jjjnettie (Jeanette)]

I'm wanting to add some focal length to my ed80 and sw120.
I'll be using my DSLR and Gstar-Ex cameras with them.
Which Powermate would be the best choice?
1.25" 2.5x or the 2" 2x.
I know that I'd get away with the 1.25" with the Gstar but I'm concerned that there may be some vignetting with the dslr.
Or would just a plain old 2" barlow do the same job at half the price?
Or should I just buy a scope with longer focal length?
Thanks in advance

JJJ,
If you intend to do some imaging with the set up, I'd go for the x2 Powermate (and get the special matching T ring adaptor)
If its for the occasional visual observing the Celestron Ultimate Barlow would be a good choice!
I've recently replaced all my barlows with Powermates for solar imaging... they work for me!

Yep 2" to prevent vignetting with the DSLR.
