Stargazing with both eyes brings an amazing amount of depth to each view while also making observations more relaxing and comfortable. Views of everything from lunar craters to wispy nebulae will take on an almost 3-dimensional feel in the GiantView BT-100 Binocular Telescope. This impressive instrument's 100mm (3.9") aperture objective lenses gather over 56% more light than large 80mm astronomy binoculars, so you'll be able to see more objects in the sky with greater clarity. But the fun doesn't stop at sunrise! During the day, this big binocular telescope becomes the ultimate "spotting scope" for terrestrial exploration. Set the BT-100 up on your deck or at your favorite scenic overlook to enjoy awesome long-distance views. The 45° angle eyepiece holders make both daytime and nighttime observations comfortable.
The GiantView BT-100 Binocular Telescope includes a pair of 18mm 65° flat-field 1.25" eyepieces which provide 31x magnification and a 2.13° field-of-view right out of the box. The included eyepieces are threaded for use with like-sized filters which can be used to enhance observations (eyepiece filters sold separately). Individual eyepiece focusers provide precise focus control, while compression rings hold inserted eyepieces securely in-place.
One of our favorite features of the BT-100 is its ability to accept pairs of interchangeable 1.25" eyepieces so you can control magnification depending on your observing goals (requires two 1.25" eyepieces of the same focal length and optical design, sold separately). For example, a pair of 10mm eyepieces will deliver a 55-power view through the 550mm focal length BT-100 (550/10 = 55). For the best results, we recommend using pairs of 6mm or longer focal length 1.25" eyepieces with the GiantView BT-100.

Mikey Smith horizontally appozed on you tube has taped Betelgeuse, Sirius, Orions belt, Capella and Vega with a green coil white base and twinkling colors with binoculars
love it
this would be great in the city at night.
Curious, could I make out the blue/green color of Uranus with these?
so im on the fence..i want a binocular for stars planets etc. im between a choice of orion and SkyHawk 9800 ,,any suggestions of which one is the better way to go
Matching my existing Monster mount to something like this is getting more attractive by the day vs. buying an APO of similar price and aperture. Nothing beats my binos on a zero gravity chair on a summer evening. I also just purchased the VersaGo II. So, the BT-100 looks like a natural fit. Is there a way to mount a deluxe red dot finder on the center of the binos? I saw some holes near the handle. Thanks
Contemplating purchasing, any updates?
thnx
John
So question what would be the cost of such an item scope only
Seems like it shook quite a bit on that mount/tripod.
Where can the nebula filters be purchased? 🧐
But...do the binos come with a neck strap for field usage for deer hunting? Jk!
Lol.
looks awesome time to upgrade my 20X80 Triplets.
hıı bro indicates how many km
indicates how many km
plz tell me maximum range any binoculars kilometers available in market 1000mm mean 1km is too short range
After what magnification CA become a problem with this binocular? Also is it possible to use filters to reduce CA, like on any other refractor?
I wonder if I could jerry rig a couple of astro scan telescopes to act in unison for stereo viewing.
hunters do this with spotting scopes, they call em 'big eyes'. A custom bracket enables collimation and alignment to produce giant binocular
You could... but would just need to ensure they are perfectly aligned... otherwise you will be looking at two different images which will drive you bat sh*t crazy
are the prisms BAK-4, if not what then?
I notice that tripod has shakes and would never use that bino on it because it would drive me crazy. I think the twilight 1 mount would be far better to use.
Jelloscope.
@@rv4891 lol
The stock 18 mm eyepieces give around 31x power and you mentioned going higher power with different eyepieces. Is going lower power also possible? And are there effective limits for lower power before the geometry of the light path gets in the way?
I own these binoculars. I use the APM 24mm UFF eyepieces to provide a sweeping 2.8° field. It's a great combo. Under dark skies dark nebulae pop into view!
I had a Monster Parallelogram mount which was recalled and I ended up buying it again with Orion's modifications (I'm not sure what was changed actually). In any case, the BT100s are 15 lbs. Though the Monster mount is rated to 15lbs capacity, is it wise to tax the mount at the very limit of its capacity? It looks steady but some parts are plastic and can crack eventually.
Thanks
Hi there! The BT-100 clocks in at just about 14.5 lbs and you are correct that the Monster Parallelogram is rated at a 15 lbs max. Even as the weight of the BT-100 approaches the maximum payload, it would still operate and work fine together. We actually list the Monster Parallelogram as a recommended mount for the BT-100 and it's robust and stable enough to support this great bino.
Price range ?
Thanks for the vids - I’ve been learning quite a lot from you - I couldn’t help but notice the wobble on the binoculars there when you moved them - is that normal? Thanks
Goodtimes yes its normal
how can I buy this from European market ,specially from Italy ..?
We do not currently carry the BT-100 in our EU warehouse, but our dealers can place special orders for specific products, and there is an authorized dealer in Italy: bit.ly/2LCJqEv
how clear will the caters of the moon show?
buy a pair of 200$ 10x50 binoculars and you will get a beautiful view of the moon and some of its creators no need to spend thousands on this thing!
@@jamesfulcher8977 10X50 it's nothong when looking at the Moon
Hey, Ken. I am seriously thinking about getting a BT-100 and have a question. Can I successfully use 2X Barlows on it?
Tony Kibbie no u can't
@@jimibarker2744 Please explain. If you consider what binocs are, they are really just two refractor telescopes stuck together. You can use a Barlow on a refractor with no problem. Perhaps I just answered my own question.
@@krashunburn have you ever used a Barlow on an F5 refractor, Also did you bought the bino or not?
@@georgepopescu1327 I didn't buy the bino.
@@krashunburn well i might do it , i have multiple telescopes but I love my 20x80 Celestron so I think this should be outstanding for lunar view and some DSO on dark skies but also interesting for terrestrial.
In 1981, while running the HS Planetarium, I remember asking the head physics teacher at my High School why they didn't have binocular telescopes. I distinctly remember him saying it was impossible to line them up accurately enough. Was looking at mirrors to grind in Scientific American to build one of my own, and he took the wind out of my sails 😆.
Collimation of both sides can definitely be a challenge, we generally don't recommend using high magnification eyepieces with our binocular telescope models for that reason. The RB series from JMI sounds like a commercially available version of your idea though, those are cool looking telescopes!
I recall that in 1990 or '91 at the Texas Star Party at the Prude Ranch, one amateur astronomer had coupled together two reflector telescopes (I think they were 8")for a really different look. As I recall, you looked down through the eyepieces as the scopes pointed up at the sky. So, it can be done. Got to be a pretty neat view!
Isn’t there a giant binocular telescope in A observatory now
what tripod are you using for it?
NeverMind! Just look up Orion binocular mounts people!
Pointing it at a decent object up high ha have fun with back problems
This is Chacheng Oo from DBL Group, we need below One PCs Orion Giant View BT-100 Binocular Telescope

Go good

Can you take photos with it ?
VITA kyo It’s a binocular, not a camera.
@@Burps___ yeah,but he said astromy photogrphy
Yes you can. There is an adapter for using the camera on your cell phone. Personally,I don't like those setups, but they do work if you are patient (not me).
@@batquad8889 phone adapter is sometime can cause image not be stablilazed) cause by hand torch phone or move mount
@@detectiveamevirus8 you'll get no argument here. But, you can take pictures, especially if you mount on a decent tripod. The big thing is that a person doesn't need to spend a fortune to get involved in the hobby. If you want to go bigger, you can. But, if this is good enough, or you find you don't like it, no more money need be wasted.
Hi Ken. I am buying a Orion BT 100,just wondering would 20mm Plossl Lens or 15mm Lens suit the wide field view , or would ZOOM Lens be better !
Zoom lenses are very convenient, but generally have a narrower field of view than fixed focal length eyepieces. A 20mm Plossl will have a similar field of view to the 18mm eyepieces that are included, if you want a wider field of view something like a 32mm Plossl might be better.
I appreciate that you asked this question at least one year ago… but surely it would be difficult to synchronise two zoom lenses to exactly the same magnification wouldn’t it…? 🤔
how much magnification ?
Not available at the moment, Orion has apparently ceased to exist.
@@michaelatkinson4416 i asked question not about aviable or not , how much magnigication ,,, just : )
@@demetrea05 The Binocular Telescope allows for changing the eye piece. Therefore, it is no a fixed magnification. I have a different manufacturer BT-100 ... it has focal length of 560 mm. It comes with a pair of 14 mm eyepieces ... the formula is 560 / 14 = 40 ... (focal length divided by eyepiece equals magnification) I also have 22 mm eyepieces which results in 25.5 magnification ... and 7 mm eyepieces which results in 80 magnification. Going to smaller eyepieces can get into collumation challenges. But I know some people go to 5 mm or 4 mm eyepieces.
@@michaelatkinson4416 understand, TY
14.5lbs…beefy. Good one.
$2,200,00 on the tripod shown.
I feel like a few hundred bucks at Home Depot could buy enough stuff to make a very sturdy stand.
Now, this rig will set you back #3,500.00. Two years and a 30% price increase.
they should of made them 150 mm what a waste
should have
Can someone sponsor me a decent binoculars for stargazing, I've got a Orion sky-master its 25×70 magnification, but I want to view objects much further, I've recently developed seizures so I can't even work that much again, and stargazing is more than a hobby for me..
Any reason you wouldn't want to just get a nice telescope instead then?
@@MCWaffles2003-1 I would consider a telescope as will, but its because binoculars are more mobile, but I'd have no problem with getting a decent telescope...
when they start requireing their own stand to hold steady theyre about as mobile as a telescope anyways. Anything in the sky in particular you would want to see?
@@MCWaffles2003-1 I'd like to get a better look at the Andromeda Galaxy, and the small and large Magellanic clouds, and better views of Jupiter 🙂
For andromeda you dont want much "zoom" since it is 4x bigger than the moon but lots of brightness (big aperture). Honestly though a normal camera on a tripod with a 300mm lens would give you great views on 30 sec exposures.
For planets I would suggest looking into a schmidt cassegrain or maksutov cassegrain. At least 1500mm focal length and as much aperture as you can afford. focal length = zoom and for planets (since theyre bright enough that getting enough light doesnt matter) aperture gives you resolution

Uh...many of us are interested in the specs and details of the equipment. If you want images with no dialog, there are plenty of sites where you can go.
