Not to hijak, but BB I have a question for you. I run the standard ATM 65 and like it quite a bit. Would it be a significant upgrade to add the Swaro WA piece or should I think about unloading the standard and starting over with all the (perceived) upgrades in HD glass and lower price points? The one thing I like about the Swaro WA is that it's adjustable versus something like the Vortex fixed. Sorry for the hijak!
Gman, I prefer the HD versions because I am sensitive to Chromatic Aberration, I glass in high-contrast situations (especially snowy burns) a lot, and I digiscope very often.
I would much prefer a WA Zoom like the 25-50 over a fixed WA eyepiece, because they are more versatile.
With Swaro ATM/S spotters I like the 25-50 on the 65mm spotters, and the 20-60 on the 80mm models, since the magnifications make the best use of the objective sizes, IMO. To me, it is still nice to have those extra 10 x's to make full use of that 80mm objective, when conditions allow.
The 25-50 would be an upgrade for your existing scope, in that it is much, much wider angle than the 20-60 at similar magnifications. While it will not eliminate CA in your scope, if you already like the performance of your ATM 65, I would guess you would prefer the wider 25-50 eyepiece.
A 25/30-60 WA would be even better on the 80mm, and I am glad to see the new ATX 85mm is of that configuration. I am anxious to see one.
Hope that helps.
