Excellent explanation thanks! Something that I've observed is perceived magnification. When I use my 20x80 binoculars on the moon, it's perceived size to my brain in stereoscopic view looks as big as when I look through my 8" sct at 50x (monocular view) I'm not perceiving more detail at 50x. My brain registers more detail in stereoscopic vision. Test yourself with an eye chart. You can see greater detail if you use both eyes, rather than just one. Our brains are designed to process data and make sense of what we see with both eyes simultaneously. I believe that's why people see more detail with a bino viewer.

I don't think it's just the amount of time at the eyepiece that's making the difference. There's also the fact that your visual processing in your brain seems to work better overall if your using both your eyes to view something.

I think the same as you. Having both eyes makes the brain complement the images. It is like having two pictures taken at the same time by two cameras, and putting the computer to make a single image, using the best portions of the images collected . It is easy to make a test looking the phone screen. Try to read a text on it a little far away, then close any of your eyes. Many times it is possible to note that with both eyes the image gets more clear than with one eye closed. The brain mixes the images to make a better one.

I don't either by the time explanation. Having used binoviewer for a while now, you immediately when you put your eyes to the oculars recognize how much more of a "complete image" you get with it compared to single ocular viewing, it does not take any time at all to draw that conclusion.

You are a very good teacher, thank you sir!

Why more detail w/bino viewer? Answer: Binocular summation. Two eyes together are greater than the sum of their parts. Corollary: No two eyes see exactly the same.

Nice tutorial - though he missed the benefit of bino viewing that comes from averaging the flaws in each eye. Each eye has its own individual flaws - some folks are lucky enough to have two perfect eyes - most not, so averaging two inputs really helps.

Yep...my floaters make one eye really bad, two eyes much much better

Just pick up a good ol' eye patch makes the whole process easy

Very nice intro to Bino's - Just bought one and you answerd all my concerns!

Wow! That is one well-spoken presenter. Thanks.

Mr. Dalby, I love your videos and descriptions of astro accessories. Very informative for everyone starting with astronomy and even astro photography. You have a dream job. Thanks a lot

Excellent!

Always good videos thanks

If both eyes are used, more of the brain (which is where we actually see) is involved. Just a thought.

Excellent explanation. Thank you.

Just want to say I really enjoy your site. I use binoculars as a start up and watching your site has given me confidence to upgrade. Looking forward to my first telescope.

Great tutorial. I own a celestron binocular viewer that I use with 25mm eyepieces on a celestron se8 SCT and a light pollution filter. Great experience for deep sky viewing and highly recommended.

Now that I know they’re a real thing (I’m new at this) I need a light pollution filter!

Binoviewers are also``Off-Axis Systems for your C.C.D. Cameras Autoguiders but not DSLRS,wether Orion Starshoot Autoguiders or Celestron NexStar Autoguiders``.Simply use either the Left or Right 1.25``Binoviewer Eypiece holders in place of your 1.25``nose C.C.D.Cameras &use the other1.25`` Eypiece holder for your``Guiding Autoguidance Orion Starshoot Autoguiders or Celestron NexStar Autoguiders.This setup removes the need for an``Off-Axis Guider for Astro-Photography, just use your Binoviewers.!

The improved is vision is also each eye playing off it's strengths. As each eye is not equal in all categories. For a fact my one eye sees some color more vivid while the other is sharper. I finally had success with a linear binoviewer on my 12" dobsonian.

Excellent explanation, amusing, yet informative

thanks

hmm, are eyepatches a viable solution to the squinting problem?

Awesome! Question, if I use a binoviewer on a maksutov cassegrain telescope, will I need a star diagonal or an erect prism to keep the image the right side up & correct left right? Thanks in advance! :)

Great report. Also, its nice that only 1 Barlow is needed for the Bino viewer and not 2. True, that the need for 2 identical eyepieces on the Bino viewer can be a bit expensive though, but both eyes will be happy then.

by the time i got my telescopes i was already used to using one eye because one of my eyes has astigmatism so i have to close that one when i use binoculars

Good info. Ik think that using two eyes rather than one is like doubling the size of a imaging sensor of a camera. In fact with two eye's one uses two times the area of the retina AND one uses both parts of the brain. Of course with the brain it's not as simple as that because the info from the eyes are crosslinked but there is surely a benefit in the amount of info going to the brain.

What about 2 scopes in tandem, on a heavy mount and linked by a double diagonal that the bino-viewer attaches to. Would that be a possible arrangement?

I have a SkyWatcher Star Discovery 127/1500 Mak-Cassegrain Telescope ... can i use a Binoviewer with It ? Please ... is it worth with that Type of Telescope? Please

You should be able to. The measurements of all eyepieces should be consistent where they’re inserted so when he showed us the Bino eyepiece it looked to be the correct size for use.

For me, using one objective is like trying to hop on one leg. Using the binocular adapter is like walking with both legs.

Extremely helpful video. I would also suspect that with both eyes involved, you are doubling the visual processing power.

How much focuser height change after inserting binocular head?

@RocketPlanet

Hi there. About 100mm (4") in the case of the one shown in the video (Orion, Sky-Watcher, et al). That means you will need this amount of inward focuser movement to accommodate the device. This is easy enough for all SCTs and bigger Maks, but only the biggest Newts and long focus refactors (c. 1000mm +) have this degree of focus position latitude built-in. Virtually no popular short focal length refactor can accommodate a binoviewer (BV) unless you employ a Barlow lens or at least a Barlow lens head (attached to the BV nosepiece) - and that means giving up prime focus use. Shortening the OTA tube of shorter refactors might be a nicer if somewhat harder solution. I hope this helps. KR RJD A&NTV

Hi Robert, excellent tutorial on binos but I must say, I disagree with your comments about binos and reflectors. It might take a little more effort to initially get it set up but he views are very rewarding. I use my binos with 6" F8 refractor as well as my 16" F4 reflector with no issues whatsoever.

+Sergio Figuera I'd always heard not to bother with a binoviewer on a reflector. However, I was pleasantly surprised with my results. On my refractor, despite all the focus travel I still need a 1.6x barlow. My short focus travel reflector works great with just a 2x barlow. With 20mm eyepieces in the binoviewer, it works out pretty well overall!

how does a single image become two image.wouldn't the brightness of the image suffer?

Ive got the Omicron binoviewer. Its a game changer.

Or buy big astronomical binoculars like 25x100 :)

Juggling 2 inch diagonals is fun...till it all goes wrong. :P Neat toy. I want one so I can ignore it most of the time. ;>

There is a solution for spotting scope those who want more field of view and clarity

50 percent of your brain is dedicated to processing visual information. Not only do you have the visual cortex, but visual information is important for everything ranging from balance to concentration. Watch somebody do something completely non visual like mental math and you will strangely see that their eyes often get involved. It’s hard to quantify the computational specs of your brain, but using two eyes is core to the human visual experience. It’s as simple as that. This is the main reason why binoculars exist in the first place.
