New visual back - useful?
Posted 22 January 2013 - 11:43 PM
I recently added a 12" LX200 GPS to my stable (I got a great deal on it used, its my first SCT) and I am considering buying some additional eyepieces. One is likely to be a longer focal length (>35mm), wider-field eyepiece (68 degrees? 72 degrees?), probably 2" (all mine are 1.25" now). To maximize the performance of the new eyepiece, I am considering replacing the visual back with a 2" version as the back that came with the scope had only a 1.5" aperture (but the microfocuser and diagonal are 2"). From what I can tell the one product out there that does this is the "Eye Opener" for around $70-$75. This isn't cheap for a pretty simple threaded ring...but I'm willing to pay if it really makes a difference.
Has anyone had any direct experience with these? Did it make a noticable difference? Worth the purchase? Recommended?

That looks like a cool item, but I don't think the electronic microfocuser would thread onto it...
What microfocuser are you referring to?

Astrophysics also makes a 2" adapter, and that is the one I'm using on my current scope, a 14" HD. Not expensive, and very nicely made.
