Questions & Answers

Rich V : Are they good for looking out 10 miles into the ocean?
MARC C : Can you attach a DSLR camera to these with a tripod for astrophotography?ROY C : You will need an adapter specifically made for mounting to the binoculars and a high quality tripod. They are very heavy and almost impossible to use without a strong tripod.Philip E : First, SLRs are not as ideal as mirrorless due to the extra vibration from the camera mirror flipping. You would need an “over the eyepiece” device with a compatible ring adapter. They exist but I am not sure it will fit well and grab the eyepiece. The weight of the DSLR would be unwieldy. If you have a decent smartphone camera there are easier devices for mating it to one of the oculars, then use the other ocular for locating and focusing. If using the DSLR, center of gravity will be an issue and to where you attach the tripod. To the camera, to the binoculars, both??? Bottom line, a lot of effort and the various factors will likely degrade quality. They are great binoculars, but I don’t think they are great for astrophotography. I did not research this too much, as I have other options with my telescopes. Others may have been more successful. I would worry that the fittings would be under to much stress and damage the camera or it will fall. Best of luck for viewing!
Shopper : I have these binoculars and am unable to get them to magnify. HELP! They show Mars as a small pinpoint dot even though Mars was at opposition when I was looking. What is the problem?Manny P : There is no problem You need a telescope , not binoculars , for planets The best you will see is Jupiter, as a large white pinpoint with four tiny pin-points in a line on either side of it which are its moons, and you may be able to make out the rings on Saturn as a little fuzzy line on either side of it, but with Mars all you’re ever going to see is a reddish pinpoint

eclipse up close

It?s very heavy and much bigger than anticipated but gave us an incredible view of the lunar eclipse. The built-in tripod mount is also very helpful.

Very Enjoyable

I keep mine mounted on a large tripod and close to my front porch on the east side of the house. The full moon and various star formations are a real joy to observe on a regular basis. This is my second set, the first set was stolen.

Superior Function at Bargain Price!

I shoot High Power rifle. At 600 yards the spotting disc appears to be right in front of you. The Great Galaxy in Andromeda is awesome! Mars, Antares, Betelgeuse, and Mars all look like red stoplights. A full moon view is fantastic and nearly blinding. You can count the mites on a gnat's backside at 300 yards. Folks, for the money you simply just can't get it any better. You want better? Then dig up $125,000 for Canon's most expensive telephoto lens and you'll get better! MY bet is that for the money spent at Adorama, unless you get extremely lucky at a garage sale or inherit the big Fujinon binoculars, you WILL be happy with this. We bought a pair of 11x80 Celestron's for Halley's Comet, and after all these years they still give excellent service, have never required servicing, and those unfamiliar with big binoculars still commet on what an excellent view and ease of adjustment they give.

Bought Celestron's for Halley's 5*'s

Weight and bulk are the downsides. But unless you have $125,000 dollars to buy the Fujinon in this class....Yes there are better products in this class, but unless you are very serious and spend a lot of lens time, these will do just fine for 99+% of users. Now, if we can just get some clear night skies,the Great Galaxy in Andromeda (M31) should be be a fine beginning.Betelgeuse, Antares, and Mars ought to look like stop-lights

Pretty fantastic

I bought this for my husband as a Christmas gift. He wanted some good binoculars for star and planet gazing at night. Reviews told me these were the correct choice, and they were right. They are heavy and a bit unwieldy, but a good tripod will sort that out right quick. The first night we took them out, I thought we were looking at Mars and I couldn't sort out what some tiny little dots near it were until I realized we were actually seeing Jupiter and its moons. Earth's moon looks just fantastic through these too, and Saturn's rings can even be seen. I completely forgive them for seeming excessively large given what they enable us to see. ...and I searched pretty much the whole internet for the best deal. Adorama had the best price by far. They shipped them quickly and securely - I was very pleased.

Good option, great value

I bought these for my son instead of a first telescope, and I'm glad I did! Collimation out of the box was perfect. Great views of the moon, as well as Jupiter and Saturn. Great for open clusters, ok on the brighter globulars. FOV is a bit narrow and they are heavy. Orion XHD tripod with binocular mount barely handles them, but remember they are 100mm binos. I also got a set of solar filters which work nicely with these binocs. Excellent for the money!

Great views, but Huge

These binoculars show great detail, but require a tri-pod and work best for stationary objects. The moon viewed through them is absolutely awesome. I have had trouble seeing much detail of planets or star clusters. However, I have not had them out yet in a non-light polluted area.

affordablity

Simply put, any 25x100 affords the astronomer a unique fov not capable in single lens scopes. It truely is like using two single scopes for each eye. Exceptional planetary views and incredible dept of our moons lunar surface. During dark clear nights,these giants reveal many objects otherwise unseen throughout our milkyway. All binocular targets displayed in my charts are easily observed through these giants but you need a steady tripod for panning and suppporting these 10lbers. For the money?..well, my eyeglasses cost 100 dollars more than these and all i can say is i feel i got my moneys worth! These are built using a hell of alot more materials ,backed by incredible engineering and even backed by a limited lifetime warranty for just over a few hundred dollars! can not go wrong.

Excellent Quality but it really is heavy

Arrived well packed both from manufacturer and seller. Nice storage case. The optics are of excellent quality, especially for the price. Construction is solid as it basically has to be. It really is heavy. Too much for most of my tripods and even my heavy duty one barely handles it. The great view makes up for a lot of the handling problems tho.

Field of View (Degree Angle)

Field of View per Manufacturer is 3.0 degrees, BUT based on actual observation of star fields and comparison with detailed star atlas, the field is really about 2.3 degrees, certainly less than 2.5 degrees.
