The Stereo Binocular Viewer will also improve contrast on deep sky objects as well as solar system objects. The Stereo Binocular Viewer isdesigned to work with Schmidt-Cassegrain telescopes (SCT) and many refracting telescopes

A substantial piece of equipment


from Chicago Heights  -  Avid Adventurer

Once you understand that this piece of equipment requires the purchase of two telescope eyepieces of equal power then the piece of starts to make sense. Once you understand how it works it is a pretty good product. It does have a learning curve. It also comes with a very nice storage case, but the case doesn't have room when the eyepieces are loaded.

Wow, Wow, Wow. AMAZING


from Agua Dulce, CA  -  Avid Adventurer

This is how the heavens are supposed to be viewed, with two eyes! The comfort of observing with two eyes vs one cannot be overstated. You look longer and can more easily notice details you might otherwise miss. I took these to a recent star party where we share our equipment and expertise with the public. My astronomy club has many impressively large telescopes, but I have to say that all the kids, parents, and grandparents that looked through these binoviewers came away with huge smiles, wonder on their faces, and gasps of amazement. The 3D effect on Saturn startled them in some cases to disbelieve. One 10 year old boy looked through the scope and then came around to the front because he thought I was holding a photograph in front of the lens to trick him. Crazy but true. I want also to share the one limitation of these and all binoviewers I think. They perform best on brighter objects. If you are searching for a faint fuzzy you will do better with out binoviewers. I use these with a Celestron SE8 telescope, a pair of 25mm, and 15mm Plossl eyepieces. Really, the bang for the buck is a great value. Opens up a new amazing way of viewing the heavens. Don't miss it.


Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Will this viewer focus properly if used with a "rich field" refractor, 600 mm focal length (f/5)?
JOEL L  This is a telescope and mount complete unit. It is not aunit to be used to "focus" another telescope. If your question is if you could secure a refractor a refractor telescope on the mount then you would have to check the weight of the refractor and also insure that the telescope has a compatible mounting system.
Shopper  Do these have inter-changable lens? Has anyone tried using them on a PST solar scope?
Andrew R  This binocular viewer does not include, but does require identical eyepieces and is designed to work with Schmidt-Cassegrain telescopes (SCT) and many refracting telescopes.
