Listing is for LEICA Binoviewer for Telescope with LEICA 10x/22 eyepieces. These are from Leica microscope's head and permanently adapted for using in telescope.
It comes with 2 adapters to use regular 1.25" telescope eyepieces in the binoviewers.
I converted them to use in telescope with necessary adapters and 1.25" nosepiece. It works great with binoviewer friendly telescopes (like cassegrain & maksutov). Other telescopes either needs optical glass path extenders (expensive) or barlows (changes magnifications). Best would be to use a tele-extenders like Televue Powermate or any telecentric barlows. Or else there are big brand manufacturers that makes optical glass path correctors.
* Comes with integrated 10x Leica microscope high contrast eyepieces (25mm equivalent).* 1.25" nosepiece adapter to put in a binoviewer friendly telescope.* 1.25" nosepiece can be removed and it got T2 female thread (which can be adjusted using hex screws). This can be used with Baader T2 prism to decrease the glass path.* Eyepiece can be pushed in/out to adjust diopter.* Field stop is razer sharp. Excellent contrast without any false colors.* Uses pretty high quality beam splitter* Uses mirrors for redirecting the light to eyepieces* About 22mm aperture to the telescope side.* Collimation is good when testing. But it can be easily done through tiny 3 screws in the side of those eyepieces.* Tested using my Celestron C6 on Jupiter and Saturn and excellent. Due to 22mm field stop in 10x eyepiece (25mm), it got limited FOV. But works exceptionally good for planets, double stats.* The alignment is tested and looks good. But if you face trouble merging images with regular binoculars, these binoviewers are not recommended.
P.S. Eyepieces can be swapped with any pair of 30mm base microscope eyepieces. Also It comes with 2 adapters to use regular 1.25" telescope eyepieces in the binoviewers.
Also need to be careful when using this binoviewer. The eyepieces are not screwed or tightened (as done in normal telescope binoviewers). So, they might fall down if the binoviewer is tilted down improperly. Need to always hold the binoviewer in such a way that the eyepieces are always upside.
