## Description

This adapter allows you to attach binoculars to a tripod.

Review: Seben service and eyepiece quality both brilliant! - I ordered a Plössl 40mm and a Barlow from Seben in Germany at the same time as placing an order from two other items from inland (UK). Within just a few days after Christmas, the Seben order reached me two hours before the inland UK order got to me! So top marks for Seben's service; the lenses arrived securely packed - the Plössl was in a good plastic screw-down pot. The lens quality is great. For the money, these are surely unbeatable. We were given a Celestron 114mm Newtonian 'scope for Christmas. These lenses, plus a Telrad finder, have converted the Celestron from a frustrating bit of kit into a fun, easy to use and good-quality backyard instrument. The Plössl gives us fabulous views of Jupiter and four moons plus two cloud bands; with the Barlow we can see the Great Red Spot too. We have fab views of the Orion nebula, the central smudge of Andromeda Galaxy and the spread of the Pleiades, all in one hour of viewing. Fabulous. Can't wait to get out there often. As an amateur, and having used binoculars on a tripod previously, I can say that the Seben service and the very adequate quality of their Barlow lens and the Orbinar Plössl lens make me happy to buy again when I need to augment my lens set, as I surely will.
Review: Reasonable Optics for Price but in practice difficult to make full use of potential Field of View - Bought this eyepiece to obtain a greater field of view than the 32 mm eyepiece currently had, for general deep sky observation with my 203 mm Dobsonian reflector. The build and quality of the optics seemed ok for the price. However I did discover the problem relating to long focal length/low power eyepieces i.e. your eye pupil diameter being insufficient to make full use of the aperture of the scope. I have since read that if you have a 'typical' persons 5-mm eye pupil, you cannot use an eyepiece longer than 30 mm focal length on any f/6 telescope, if you want full use of the aperture. The focal ratio of my scope is 1200/203 i.e.nearly 6. I found the distance of my eye from the eyepiece very critical in obtaining a reasonable field of view, if you moved too close or far away the field of view was seriously reduced. Was very difficult to maintain the optimum position. This is where a rubber eyecup to provide some eye relief and cut out extraneous light may have benefitted. For some reason one is not fitted whereas my 32 mm and smaller eyepieces all have one. Also lacking were any push on cups to protect the ends of the eyepiece when not in use, most other eyepieces I have bought have these in addition to the packing box.

### ⭐⭐⭐⭐ Good Eyepiece and a good price
*by S***S on 16 December 2012*

Delivery was fairly quick (week and a half) considering it was from Germany and coming up to Christmas. The eyepiece itself looks very well made and gives great wide views with my f/7.9 scope. I will probably buy more
