I do have them on several scopes - but only as finders. Tried a variety of other eyepieces and came back to the standard crosshair one provided with the finders.
I've had the SV50 and 60mm RACI finders for years but frankly, I've never thought the scopes were all that sharp. This project is for my Altair Starwave 102mm F11 ED which is usually used on a driven EQ mount. I wanted an auxiliary scope that could take different eyepieces and had decent image quality. I have the Baader Vario, The TS Vario ED, and am now trying the AT60ED. Interesting thread! I've been on a bit of a finder odyssey over the last year or so.

However, if by "fast" you mean f-ratio then you'll have to accept that "fast" objectives usually mean more aberrations, but that may not be much of a factor when working at low magnifications.Īctually, for a simple visual finder I'd be looking more at weight, the ease of use and rigidity of the mount/adjustment mechanism (which you've seemed to address with the Azzomat), and the quality of the illuminated reticle, but I guess you could also upgrade the latter (but the selection of 2" eyepieces with illuminated reticles may be limited).Īs for premium finders/guiders, there is always Borg and the Baader Vario-Finder (both pretty expensive, but maybe "fast enough").
Sure, given any single eyepiece a different focal length objective will produce a different magnification and field of view and exit pupil, but which one of those are you using to describe as "fast" or "slow" (since those can be changed with a different eyepiece)? I'm not sure what you mean by "fast enough" or being on the "slow side" but for visual the only thing that will matter are the aperture and the exit pupil that is produced by the chosen eyepiece.
