## Description

Full description not available

## Features

- Almost 3D Observing Possible: A binocular viewer turns your telescope into binoculars; unlike the common and rather un-natural one-eye observing way; you can observe in a fully relaxed manner without squinting and experience a stronger sense of space
- Equipped with Two Additional Eyepieces: The device comes with two 1.25 inch 32 mm Plossl eyepieces secured by compression rings without scatching them; a stereo viewer requires a matched pair of 1.25-inch eyepieces; other sizes are sold separately
- With 1.85x and 3x Correctors: Two glass path correctors are offered; they multiplies magnification 1.85x and 3x like a Barlow lens but it will allow for proper focusing; with these two glass path correctors; more telescopes can be adapted
- Multi Coated BAK4 Prisms: The BAK-4 prism is equipped with multiple layers of coating on its optical surfaces; aiming to minimize reflection and enhance the contrast for deep-space or solar system objects while reducing light loss
- Compatible with Various Telescopes: A novel optical system simplifies the focusing process; even when using Newtonian telescopes; short refracting telescopes and Schmidt-Cassegrain telescopes

## Questions & Answers

**Q: Does this one come with two 30mm eyepieces?  I don't see them pictured and they are not mentioned in the description.**
A: Yes they do come with two unknown mm eyepieces. Use quality plossls of same mm. LOA recommended.  21/32mm

**Q: Does it attach to the gskyer telescopes? And work better?
Thanks**
A: Short answer, yes. Just like an eyepiece, the binoviewer slides into the 1 1/4 inch tube and you tighten it in place. You then put two identical eyepieces into the back of the viewer. The biggest "improvement" is that it will give your brain what it wants-a stereo view. 
Our brains do not like seeing through one eye. This piece of equipment means you don't need to squint your eyes or do other things like that to see through the telescope. To some it is a huge difference and you see much more naturally. I love them! Biggest thing is to have two eyepieces of same make and power. You can just buy a pair at a time or you can buy, say, two kits like Celestron has with a range of eyepieces depending on your budget

**Q: I want this but it costs more than my telescope. is it worth it?**
A: IF YOUR TELESCOPE IS WORTH THAT MUCH I DONT THINK IT WOULD DO THAT GOOD FOR YOU
IN SEEING OBJECTS

**Q: what's the IPD?**
A: Inter Pupillary Distance.  It is the distance from the center of the pupil in one eye to the center of the pupil in the other eye.  The Bino-Viewer is adjustable and the distance from the center of one eyepiece to the center of the other eyepiece should match your IPD.  Simply put, lining up the eyepieces with your eyes, similar to conventional binoculars.

## Customer Reviews

### ⭐⭐⭐⭐ Pretty awesome!!
*by S***E on October 30, 2024*

I purchased these and the CELESTRON model and inevitably chose the more expensive CELESTRON ones but only because I love the brand and they were a bit higher quality. This brand was just about the same and I’m sure would do the same thing… but I did not receive any eyepiece like they advertised and they just seemed a little less solid to me. But if you’re tight on money then these are good. Also just for reference… they do not seem to work with any eye piece angles or on Reflector scopes…. I may be wrong though and just not have figured out how yet but thought it worth sharing.

### ⭐⭐⭐⭐⭐ Quality product at a good price and exactly as described
*by C***I on June 9, 2023*

Tested with F5 achromatic refractor. Not the ideal telescope. Very good image of the moon although it did not focus directly, if it did with both barlow lenses included. Saturn although small, its characteristic is noted. It was also tested with svbony 17mm plossl eyepieces. At the moment with this F5 telescope, I don't think it's necessary to try more lens combinations.UpdatedAfter more than a year, I will explain according to my opinion why they are not for everyone.Sometimes I have not been able to emerge the image. But more than once I have achieved more than 240x on the moon. They have worked well on planets and some nebulae and open clusters. Sometimes small objects do not emerge but large ones do. They improve contrast at the expense of less light, although in general the image is more relaxed with both eyes. That is why I have purchased several sets of eyepieces that work very well on them and are not extremely expensive.svbony40 plossl25 plossl15 red line10 flat field " does not have a slot".These pieces can be unscrewed from the barrel and inverted. Then the slot would be at the bottom.Another high quality item was the oca 2x from William Optics which is sold by Agena. This provides better image quality than the 1.85 of the binoviewrs.Why give them more than one chance if the image doesn't emerge the first time?If you have not rested well even though you feel well, the image may not emerge.Do not drink alcoholic beverages before or during use. It is an excellent test to verify that you are no longer well even if you feel wonderful.If you take any medication, make sure it does not interfere in any way with your alertness. Even if you feel fine, it will probably cause problems for the image to emerge.The first time, I recommend trying during the day with some large and one small distant object. Also try starting to focus without adjusting the eyepieces and then adjust gently.At the moment all the named combinations work, some if not others, with these telescopes. In a refractor it is ideal to have, if applicable, 1.25 and 2 diagonal to be able to focus certain combinations.120mm f5 refractor105mm f13 mak90mm f5.5 refractor200mm f6 dobsonianBut if you want to keep it simple, I only recommend as an improvement, the oca from William Optics.

### ⭐⭐ Alignment issues
*by I***L on November 27, 2023*

I really wanted to get a cheaper binoviewer than the really expensive ones I had gotten years ago and had to give up for its terrible (too long light path) 9 inches! I could not get them to work on my newtonian as they were just too bulky and offsetting for the telescope. At least I could get them to focus into one image just as I can easily get binoculars to focus into one image. NOT THESE binviewers however.. I even tried 3 (I really wanted to have them succeed so much) and everyone had this same imaging problem. I and others who tried them out said these just would NOT image into one image such being a make or break for its performance. I had to send them back and got a warning from amazon on too much return of product....Just to say I won't be doing this again.
