Arcturus BinoViewer with Two 30mm Plossl Eyepieces-and-Two-Barlow-Attachments

Article number: VSV03

Our Arcturus Brand Binoviewers are new from the same plant in China that makes the same ones for other name brands such as William Optics, Celestron, Stellarvue, & Orion.
Eyepieces shown in the photos are included!
The Arcturus brand however has several important features not presently found in the competition mentioned above:

1. Our binos come with 2 screw in barlows, one at 1.85x and one at 3.0x that replace the standard 1.25" barrel.

2. There are no setscrews used on these binoviewers.  The eyepieces are held in place with self centering brass compression rings.  Brass will stand up to the weather much better and the self centering design keeps the eyepieces in good collimation with no off-axis bias.

3.  The bottom line is always the price and you will look long and far to find anything like this.  Our price is at least $50 less that any of the competition.

    Binoviewers such as these do not require the use of the barlows in order to come to focus with Schmidt cassegrains.  The fact that we give you two barlows means that there is no need to purchase any additional eyepieces in order to get a variety of 3D-Like views!


  Please also note that these binoviiewers have built-in individual eyepiece diopter correction to adjust for your particular vision.

The prisms are fully multicoated BAK-4 prisms. Every unit is tested for collimation prior to shipping and the overall quality of this viewer is excellent. What distinguishes these binoviewers from all the others is the use of self-centering eyepieces. There are no setscrews that will push the eyepiece off center collimation. Allow me to put it this way: due to the amount of glass the use of a binoviewer for astronomical purposes has its limitations. Having said that, however, the view of many, many objects in the night sky is absolutely devastating with the 3D effect it gives you! I personally use a binoviewer on a regular basis and I would hate to miss the view. Spending $100-200 on a binoviewer system is a very worthwhile investment. I am not so sure the same could be said of an investment that runs over $1000!
Hope this info helps,

With our Binocular Viewer, you'll swear you are seeing in three dimensions! * Includes thread-on 2x Barlow lens so you can choose two levels of magnification * Hinged aluminum housing contains fully multi-coated BAK-4 prisms for high light transmission * Reflectors and short-focal length refractors may require the short 1.8x  barlow lens in order to achieve focus* Includes TWO barlow lenses (1.8x and 3x) and caps for eyepiece holders and barrel.


 You were born with two eyes, so why not use both of 'em when stargazing with a telescope? Now you can, and you will be pleasantly surprised at what a difference it makes. The effect is most pronounced on the planets and Moon, but even deep-sky objects seem to have more clarity and depth. And now this popular accessory comes with a thread-on 2x Barlow lens, so you can choose two levels of magnification. The hinged aluminum housing contains fully multi-coated BAK-4 prisms that provide high light transmission. You can use almost any matching pair of 1.25" eyepieces. Individual helical focusing collars ensure a sharp focus for each eye. The viewer's 1.25" nosepiece is threaded to accept filters. The Arcturus Binocular Viewer for telescopes works with all types of telescopes. On reflectors or short-focal-length refractors you may need to use the barlow lens to accommodate the requirement for 4" of additional inward focus travel. 22mm of clear aperture.

Here's are reviews from some of our very happy customers:


"Hi Jeff,
I've been using your binoviewers the last month and they are AMAZING! Love the clamping feature instead of the screws. I left a good review on your website and have been spreading the word on cloudy nights almost every day! These are amazing!
By the way, would you happen to know the exact mm size of the opening, I am trying to get an adapter fixed specifically for these!

"Hi Jeff:
Better late than never!  My testimonial:
I purchased the Arcturus binoviewers back in July of this year, and I've used them on at least six or seven occasions so far, mainly viewing either the moon or Jupiter/Saturn. I could not be happier with the quality of the optics as well as the construction. Jeff's customer service was also top-notch, prompt and courteous. 

The two Barlow lenses work very well, and the quality seems to be good. The fixed power plossls that came with it are good quality and well suited to the task. To my surprise, I was able to get the binoviewers to work on my 8 inch Newtonian without any added accessories (i.e. star diagonal or focal point extender). 

I am a fairly experienced amateur astronomer, and I would highly recommend these binoviewers to anyone looking for a unique view of the closest objects in our solar system. I don't think you will be disappointed. "

I can't attest to the view thru bino viewers costing more....but this accessory has replaced all of my single occulars on all visual applications... I cannot get the same view with just one eye....I use them on everything from lunar to planetary to deep sky. These bino viewers give me 3D views that appear sharper then just single eye viewing-- for me I won't observe with anything else it really is a noticeable difference once you peer thru them. The customer service is excellent as well and was taken care of on items that had to be returned/defective.

It is the only binoviewer that comes to focus with PST Coronado to my knowledge. The eye relief is long. The optical quality is good for the price. I can highly recommend it to PST users.
