Which Powermate?

[jjjnettie]

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.
