Make a holder so you can wear them a bit like goggles, and I’m sold.
Genius. I've never wanted something that didn't exist so badly.
And with them on , look thru a telescope , and enhance the light gathering .... Just joking....
If I can strap these to my head, I'm sold
@@StevenDoye Did you do this?
@@wrighty338 Also curious of the outcome...
These work great and I haven’t even tried them on the Milky Way core. You can see stars in between stars.
I got excited when I saw these because it would make more stars visible in a light polluted area.
Hey Orion! One thought i have. It would be REALLY cool if these came threaded to accept light pollution filters (or had them built in)! That would really push it over the top IMO.
+1! I didn't find any infos about it...
@Aaron Hattan thanks aaron
would these be good at watching surfer's and bodyboarders, or just looking at the landscape etc
That is a brilliant idea! ❤
I have a similar pair but a different brand Helios 2x40 and they are very good and I use them a lot.You see whole constellations I had M33 in them from a dark place I was in a week or two ago.In light polluted areas they are still useful for plucking out challenging naked eye planets like Mercury and Uranus but I think Neptune is out of their reach?
is it any forcal reducer for Orion 6-Inch Ritchey-Chretien Astrograph?
Got to get one of these.
Is th center post threaded to accept a bolt for a mounting bracket? I think these would work well on a monopod. Also do we know the limit of the diopter adjustment in the focusers?
The central post is threaded for a ¼”-20 tripod adapter, but the barrels are so close together, most adapters would be too thick to fit well. But the tripod socket is present under the threaded cap if you would like to build something for it. As for the diopter adjustment, the range is -4.7/+3.7.
Will these work if you wear glasses or contacts? I read reviews where eyeglass users could not and one person said even when wearing contacts it could not be used. I can understand eyeglasses but not contacts. Please clarify.
Yes!
They work great with eye glasses ( mine are rather small profile ( not big /wide lens eye glass)) .
Also, using Alpine Innovations Bino Bandits on it makes it that much better. The entire kit..2x54 binos, Bino Bandits and stock bino neck strap all fit within the stock bino pouch..
PS..using the set up handheld is a breeze.. but supporting it on a monopod/ballhead/bino adaptor makes it sooo much better-- you'll pick up details through the binos that you would never have noticed just hand holding them..
hey Ken, can I used the orion #13031 reflector focuser on the orion sktscanner 100?. the one I just bought must have been built on a monday or friday, the focuser is real sloppy and they glued the mirror onto the rear cover out of alignment with the secondary. so I am going to rebuild it as its easier than having my friend come into town, to pick me up so I can send it back under warranty. so I am looking to replace the focuser and build a new mirror cell. amazon claims that the 13031 fits 4 inch and up tubes, but are these any better than the stock one one the skyscanner 100?. btw Ken if anyone gives you shit about going bald, just tell them God only created so many perfect heads and the rest he had to cover with hair!.
Can u please help I can see only stars in my telescope I have my latitude right 27. And the tripod facing north. I cant see nothing if I zoom the stars will go away I just see stars please help
they work great video is accurate
Hi are these any good for spectacle wearers.
OMG that is what i want to get, ive been searching wide angle binoculars, like ultra wide 4x42 and hove been searching for the possibility of 5 - 7 x 60s.....
How about eye glass?
I have no idea of telescopes. I'd like to connect a telescope having facilities like connecting it to smartphones and cameras as well as connecting it to planets. What would be it's price in indian rupee?. Please suggest me good telescope.
Now if they only came with eye glass frames so I could wear them. Next item on my list.
Get a helmet and stick one of those clamp arms used in photography. Eyeglass frames will not work with this amount of weight or the military would use them for night vision goggles.
Is there still a focus that can be adjusted? I like viewing binoculars without my glasses, but then I need to be able to adjust the focal distance.
Yes, both eyepieces have separate focus adjustments.
@@oriontelescopes And what's the closest focusing distance with an emmetropic eye?
This sounds like it would be excellent for comets!
do you guys deliver your telescope in NEPAL ?
@Nishchit Shrestha no they don't. I think best way to get telescope in nepal is tejraj.com from India.😊
What the diopter range is with it?
The IPD range is 60mm - 81mm. Diopter ranges aren't usually specified but we can look into that if you'd like more information on the diopter adjustment. They have individual eyepiece focus so they're a bit more adjustable than center focus binoculars.
Can I add filters to these? If so, would a light pollution filter help?
Hi there Mr. Jack, the 2x54 Ultra Wides are not threaded for filters.
filters only wotk on M42, M8, and M27 the latter becomes a blinking planetary. If you filter recommend skyglow in just one eye to allow more light throughput, and to see more stars with other eye.
They should come with side arms so you could wear them like glasses, and I wonder what would happen if you looked through a regular binocular while wearing them, you would get double magnification if you could focus it.
Where can I get them

Can I see the whole Orion constellation?
I think the main body of Orion is around 20 degrees, and this is 36 degrees field of view, so it should fit most of Orion.
These are great for watching the night sky. I have designed a 3d printable headset for them, but UA-cam won't let me share the model in the comments. Feel free to email me.
Bro you gotta list your email here. Send me your contact
@@TomSestilio UA-cam is pretty adamant on not posting links and info. But if you go to my channel and to the far right is the about tab. There you can confirm you're not a bot and you'll get my email. I think is has to be done on a PC though.
I would have thought the improvement in limiting magnitude achieved by these binoculars should be much better than the 1 to 1.5 magnitude quoted in the video. The gain in limiting magnitude for binoculars is 2.52 x Log(light collecting area of binoculars/area of dilated human eye pupil). If we assume the diameter of a fully dilated eye pupil is 8 mm. Then the improvement in limiting magnitude should be about 4
Doesn't work that way with Galilean optics. The magnification controls brightness, not the objective diameter.
@@RichardKinch thank you very much for your comment to correct my misunderstanding. Do you have an link you could send me to explain this a little further? I am always keen to understand more about these matters
@@steafanmaciarfhlatha8497 In a Galillean scope the *aperture stop* is not the objective lens, but the eye's pupil. From the point of view of the object looking at the scope, this aperture appears magnified by the MP of the scope, as if your eye was that much bigger. Hence the *brightness* also depends directly on the *user's pupil size* (times the fixed magnification factor), which happens to be a disadvantage for presbyopic age users, where pupils don't dilate as much as younger ages. There is no *exit pupil* in a Galilean scope to be matched to the eye's *entrance pupil*. Thus whatever brightness you see unaided, will be brighter by the magnification factor, when looking through a Galilean scope. Contrast this with Keplerian scopes, where the aperture stop is the objective diameter, the exit pupil is the image of the aperture stop (i.e., the objective) formed by the eyepiece lens, the brightness increase is the ratio of the aperture stop diameter to the MIN(exit pupil,eye entrance pupil) diameter, and an exit/entrance pupil match yields full transfer of all the light collected by the objective. See Warren Smith, _Modern Optical Engineering_ 1990, p. 246.
@@steafanmaciarfhlatha8497 If Galilean brightness == MP seems counter to intuition, imagine looking through a flat, thick pane of glass, which is equivalent to a 1X (non-magnifying) Galilean scope (the flat glass can be imagined as a stack of two elements, one positive and one negative focal length, with f_o = -f_e, in contact), if you will. The 1X brightness is the same as looking through air, and depends only on your eye pupil size. The brightness does not depend on the size of the panes of glass. The field of view depends on the apertures and eye's position (keyhole effect), not the focal lengths. Now imagine how none of this logic of brightness and FOV changes, just because you increase f_o > -f_e to realize magnification MP = -f_o/f_e to be > 1.
Another benefit of this thought experiment is that you can brag to your friends that your house's windows are actually telescopes (with 1X magnification)!
Normally it should reach mg 10 but due to the low magnification, 8.5 or 9 seems possible, probable.
I ,myself have got 2x40 mm and under medium skies, mg 4 maxi with the naked eye,...
It reached ...6/ 6.5.

SEEING THE STARS AS KITTY CAT SEES THEM. (This product is the first stab I am aware of of anything like the following memo proscribes. It is NOT the same optical system described below, but I think in about ten years, when what is laid forth below becomes possible, this product will be seen as a kind of trailblazer:
)
In addition to "naked eye Astronomy" and astronomy with a telescope, there will eventually be something which could be called, "kitty cat astronomy." Cats have something like 6x the rod cells as human eyes do, but far less cone cells, meaning they can see very faint objects, but lack the human ability to see intricate colors and detail. Cats do not have better vision than humans, but better night vision. Humans have better vision for the things they have evolved for, such as reading books and working on machines during the day. If the human pupil were a bit less than an inch wide, we could theoretically see as brightly as a cat sees at night. Orion Telescope Company has actually produced a purely optical wide angle "binocular-google" that boosts human BRIGHTNESS vision by four times. With new negative refraction metalens optics now being developed, capable of extremely short focal ratios as well as off-axis focusing, such a system could eventually be fitted into something the size of a pair of eyeglasses. The trick is getting all that aperture into an exit pupil under 7 mm wide, the width of the human pupil at maximum, in dark settings. Otherwise, that extra light is going to waste. Flat lens systems can be designed with ultra low focal ratios, such as F1 or F2, meaning that this would be possible. A pair of eyeglasses could incorporate an under-one-inch optical system, if it were thin enough. Note that it would not be the same as a simple pair of glasses, but an actual telescopic system, collapsed down into a very thin package--with magnification 1x, and brightness intensification 6x or 10x or whatever.
(This product has already gotten it to 4x light intensification using traditional lenses, with a 2x magnification, meaning that if it had 1x magnification, it would be correspondingly greater.)
Moreover, since flat lens optics can just as easily create off-axis focal planes (not down the center of the objective lens as with traditional optics), such metalens "binocular-googles" could also be made arbitrarily large. This is because the space between the eyes of about 1.5 inches complicates the size of diameters for the objective lenses. This is why binoculars have to reroute the images through mirrors or prisms, to fit into eyepieces that are the same distance apart as your eyes. However, with flat off-axis lenses, there could be a straight simple line directly to your eyes. (The focal point, instead of being perpendicular to the focal axis of the lenses, could be designed to hit near the edge of the axis.) They also need not be round, but could be oval, square or even star-shaped. This is all possible with flat, laser lithography imprinted meta-optics. With moderately larger googles we could even see as well as an OWL, or even better.

Is there an tripod mount adaptor fo it?
Hi Sergey! There is no tripod adapter, they're small and light so they're perfect for for hand-holding.
Because they aren't high zoom, they won't appear shaky.
Exit pupil of 27 mm? You can’t accept all the light.
It's a galilean optical design. More aperture for more FOV. Big difference...
In the video we talk about exit pupil at about 4:17. This Galilean optical design works differently than a standard Keplarian style binocular like a regular 10x50 with a 5mm exit pupil. This has a “virtual” exit pupil located inside the optics, so that rule doesn’t apply. Brightness is purely based on the magnification of this style, and field of view is purely based on the diameter of the lens. It's very different from other binocular designs.
Orion Telescopes & Binoculars Thanks for explaining, it is certainly food for thought.
Wouldn't these be exactly the same if they were 2x14? Ok, explanation given, and I understand.
How much is it?
$149.00
EP is 27mm. Your pupils are 5

Finally, i can become a fish
cost is $150.00... ouch
What?🤣 That's a lot for it to be so small.
Thats a good price. Good glass is expensive.
It's a very good price imo
You should see the price of the opera ticket.
Yeah these kinda comment always amaze me too, like go try to get into thermal or good quality nv. They kick off at like 3k or more if you want something that actually works.
Tripod mount is a must with those binos 😂
WHY, pray tell?? These are only 2X!
@@vishnu437 it was a joke
the new ones have an image stabilizer with batteries!
I had to get the monster parallelogram mount. These suckers feel like they are going to bend the tripod.
