While at Okie-Tex I borrowed one for the night from the Televue Rep, I've always wanted to try one. I tried it in my 16" F4.5 dob with Paracorr, but it was just way too much magnification for the seeing that night, its about 450x.
My friend has a Televue 101, which gave a much more reasonable 115x, just under 1 deg AFOV. The view of the double cluster was amazing, talk about a spacewalk feeling, if I put my hands around my eyes to block any outside light and it was truly like floating in space, I could not see the edge of the FOV. My friend said this view was the closest thing he has ever seen to using binoviewers, which I've never been able to enjoy because I'm blind in one eye.
The problem we ran into was there aren't many objects that are bright enough to really enjoy at that magnification in a small scope, even in dark skies, and we had some of the best that night. So I'm curious, those who own this eyepiece or or even the 3.7mm, how do you use yours? I can see how this eyepiece would be amazing on the moon in any telescope, but other than a few bright objects I don't see it getting much use, but maybe I'm missing something. There are those rare nights when the seeing is good and I use that much power on my dob, but usually they are small objects, but I can see how the extra FOV would be nice even if the object doesn't fill it.
