Unlike many finders that use inexpensive slide tube focusers or require screwing and unscrewing the objective to reach focus, the Stellarvue can be focused to accommodate different people thanks to its helical focuser. Merely turn the rubber grip to attain focus.

All Stellarvue optical finderscopes will accommodate various standard 1 1/4" eyepieces.  Most Naglers, Panoptics, Plossls and Kellners will come to focus although Barlows generally do not work.

Do not discount the performance of the included eyepiece. The eyepiece that comes with the finder is a high quality, fully multicoated, 23mm wide field eyepiece with 22 mm of eye relief, 50 degree field of view and a large eye lens. This eyepiece features a  focusing cross hair reticle and will accept reticle illuminators.

Customer comments: Today I just received the new Stellarvue 9x50 finder...All I can say is WOW, what a piece of work! Vic has now set a new standard in finder scopes too. It is both mechanically and optically head and shoulders above anything out there that I have seen.

The F50-2 and F50I finders were designed by Stellarvue to be the best in their class. We started with an accurately figured, fully multicoated doublet objective of our own design operating at f-4,  mounted it in a blackened tube threaded the dewshield, designed and made a BAK-4 correct image erecting prism and mounted to that our unique helical focuser with rubber grip accepting all 1 1/4" eyepieces. This eyepiece does an excellent job providing a sharp, flat field image that is nearly as wide as 12 full moons! The new 60 mm finderscope uses a larger and faster objective.  While it is not as shapr across the field (since it is only f-3.75), it gathers more light. We recommend the 60mm finderscope for use with the included eyepiece. But if you want the widest field and wish to boost power a little using your Televue eyepieces, we recommend the F50.

Customer comment: Vic, I just got the 9x50 finder I ordered and put it on my SV80L. It is a very nice unit and works great. Very impressed with the quality vs the price.

STELLARVUE MOUNTING RING SYSTEMS

Stellarvue finders mount to most 50 mm finderscope rings including the Meade and Celestron etc.  The entire back is easily removed from the finder by unthreading it. This allows easy insertion in various ring systems.
