When I received this binocular, it had been overcast day and night here in western Oregon for about 3 weeks, so (obviously) I had done no observing. Then, the day after the Zhumell 20x80s arrived, I walked out into the back patio about an hour after dark and looked up at a clear, and actually BLACK (vs our normal faded navy blue) sky; since I had no telescope ready to go, and didn't want to do a lot of hauling out and setting up, I took out the Zhumells, at this time only test-driven-in-daylight. These are big suckers. Also, fully multicoated optics which is why I opted for them over the same size Celestrons.

So I bundled up, gloves and all (about 35 degrees out), and took them out for their first real test as an astronomy binoc. I lay back in the chaise, and pointed them up to the high mid-sky area to the south and southwest. So how were these first views?

In a word: Incredible.

The optics in the Zs are brilliant, just like you would expect from what is, in essence, a double-barreled refractor: bright and sharp, superb contrast, and showing me a LOT of stars, all these elements noticeably better than my trusty Celestron 15x70 SkyMasters (which have been, and are, a superior instrument in their own right).

Moreover, I was surprised, based on all I have read about how heavy these 'nocs are and how a tripod is an absolute, at how easy it was to move themn around and see things clearly and with reasonable stability by just going handheld. I'm 5-9, 152 so no Herculean guns here. But when I lay back in the folding chaise we have out back, set my elbows/triceps on the two chaise arms (and, in a later session, on a pillow I placed on my chest) and, as per binocular observing guru Phil Harrington's suggestion, lightly grasped the barrels AT THE ENDS (where the big objective lenses are) rather than at the eyepieces end, I had no trouble at all keeping them semi-rock steady, images not jumping around at all. I was able to scan around stopping where I wanted to for up to several minutes at a time before I got arm fatigue, at which point I would just bring the binoc down and rest my arms and look around figuring where to go next. I was out for an hour-fifteen. Then I surrendered to the cold and came in.

The Pleiades (Messier 45) were awesome, just spectacularly diamonds-on-black velvet gorgeous. And whereas most of the time I can see, oh, 40 or so stars, last night I viewed well over 100 in M45, probably closer to 150, every manner of size and brightness with the Big Seven showing like something under the glass at Tiffany. It was so majestic that I almost went in to get my wife out of bed to see it. Almost. I also caught IC353 right above M45, this little distended parallelogram and a bunch of field stars I'd never seen previously. Big, bright, red Aldebaran and the Hyades were similarly sparkling, they absolutely popped, and Algol, the Demon Star, looked like a big, bright, fat blood orange. The Alpha Persei Association was so star-filled that I had trouble figuring out where it began and ended, just freaking jaw-dropping. And the Double Cluster in Perseus. W.O.W. Best view ever; NGCs 869 and 884 popped right out and, along with the adjacent backdrop, the entire FOV was just flat out saturated with stars.

My best looks ever at all of the above. And Orion. The entire belt (just barely) in the FOV, ditto the sword, wonderful nebulosity in M42, the Orion Nebula, though I didn't quite have enough magnifications to isolate the Trapezium.

I never get tired of gorging on that Orion/Hyades/Pleiades trio; ditto the Double and AP Association. For me, the ultimate in ethereal eye candy.

These 20x80s are going to get a lot of time, I can see this already. Even more so because they work, and work well, as a handheld instrument. I do want to try them out on a tripod, but still will probably prefer the freedom of going handheld. I am just surprised at how easy and effective they were to use that way.

For those nights when you want to go out for just 20 or 30 minutes, or nights when you have to snag those 10-minute windows between cloud cover or for whatever reason don't want to set up a telescope, these are what you want.

They also come with a fitted, folding hard case that fits inside the larger soft case for easy and secure transport.

Title says it, using these as a monocular is great, but using them for intended purpose is impossible. I am doomed with the collimation problem of "double image". $60 shipping, $35 duties, need to return them. It's too bad because this is the first pair of powerful binoculars I have ever purchased. If this product did not have the issue that mine unfortunately shipped with, this would be a 5/5. First impressions are important.

    Comments about Zhumell 20x80mm SuperGiant Astronomical Binoculars:

    I've purchased 3 of these. The first one broke neatly at the prism when dropped and Zhumell honored their guarantee with a $25 shipping replacement fee. Second one was a gift. The optics are very adequate and fully coated, and for the price ($119, free ship), there is no competition. The tripod mount is great and I've used mine, while walking, with a monopod. The case is two layers and very protective. Straps for case and binoculars are included (case can be mounted on a backpack) and front/rear lens caps are included as well. Very light considering the size.

      Order was received/processed/shipped promptly. Arrived via FED-X on date promised.Binoculars were protectively packaged. Case and lens covers are good match for Binoculars. This pair really pulls things in close and gobbles up enough light for good observations.

              These looked OK externally, but the collimation was way off... The left side aimed quite a bit left and low compared to the right side. I couldn't get the images to fuse even in the daytime.
              On the other hand, I was very satisfied with Hayneedle's refund policy!

              Customer Q & A

              18 Questions About This Product
              Q: "Is it only celestial or both a terrestrial and celestial binocular?"
              A: This binocular is sold as a astronomy binocular because it's magnification is very powerful at 20x, but it can be used for terrestrial applications as well.
              Q: "What is the maximum width at the eyepieces between the center of the lenses?"
              A: The maximum distance between the eyepieces is 2 7/8 inches.
              Q: "Are the craters on the moon visible with these binoculars?"
              A: Yes, and quite a bit more.
              Q: "Are these binoculars multi-coated? What kind of case comes with them? Are the lenses glass or plastic?"
              A: The lenses are glass, it comes with a hard case and yes, they are multi-coated.
              Q: "Are these binoculars hand held or must they be used with a tripod, or both?"
              A: You can use them as hand held but it will not be the easiest we recommend that you use them with a tripod.
              Q: "Does this Zhumell binocular have a tripout mount?"
              A: The Zhumell super-Giant and Tachyon models both have a built in Tripod adapter that comes standard with the binocular.
              Q: "What is the difference between a central focus and individual focus for your 25x100 & 20x80,and which is better?"
              A: It's not that one is better than the other they are just different. Central focus is a big wheel and individual focus allows you to set the binocular for your eyes with rarely having to adjust the focus.
              Q: "Please describe all the materials used in the construction of the Supergiant 20x80 binoculars?"
              A: They use an aluminum alloy for the body a BK-7 glass for the lenses and prisms.
              Q: "What is difference between bk4 and bk7 glass?"
              A: BK7 is a borosilicate crown optical glass with high homogeneity, low bubble and inclusion content. Its good physical and chemical properties make it widely used in visible and near IR range. Most of windows, lenses and prisms, which used in laser, optical system, optical communication, are made from BaK-7 glass. BaK-4 glass is for higher edge sharpness and greater brightness.
              Q: "I just bought the Meade ETX- 105 with the UHT coating telescope. Will the 20 X 80 giants give a fair competition to my Meade telescope in any way?"
              A: The super giant will give you wider field of view and fun depth perception. However, to compare it to the ETX 105 is not fair to either product. They are quite different. The binoculars will help you get perspective where the object is in the sky in relation to other objects. The Meade will allow you to hone in the object. They are complementary not competitive.
              Q: "I see you've previously stated that these 20x80 Zhumell SuperGiants have BK7 prisms. However, both of your Zhumell product listings state BK4 prisms. I have seen one other binocular site that says BK7, but most say BK4?"
              A: Zhumell's 20x80 SuperGiant Astronomical Binoculars are made with BaK-4 prisms. They formerly used BK-7 glass, but Zhumell upgraded the prisms to BaK-4 in late 2004.
              Q: "Is the L-Mount tripod adapter required/recommended for use with the 20x80 SuperGiant and your ZH-WDF4 professional tripod?"
              A: No. The 20x80 SuperGiant will mount directly to the tripod without the aid of an adapter.
              Q: "I would like to know when you look across water, will you see the heat rays making it impossible for clear vision?"
              A: With their high magnification, the 20x80 SuperGiant binoculars will also magnify any heat shimmer present in the atmosphere. That means you may see heat shimmer through the binoculars that you would not see with the naked eye.
              Q: "I bought these binoculars and I would like an adjustable tripod for them. Can you recommend a decent tripod?"
              A: We recommend the Zhumell Professional Tripod for use with the 20x80 SuperGiant Astronomical Binocular. It has a wide working height range and a weight rating of better than 8 pounds to take heavy binoculars and cameras. It's a great complement to the SuperGiants.
              Q: "I would like to buy binoculars for Astronomical, and for a general use purpose (Traveling, birding and other nature related purpose) will Zhumell 20x80 SuperGiant Astronomical Binocular be the right candidate?"
              A: Zhumell 20x80 SuperGiant Astronomical Binoculars are great instruments and a great value. However, at 13 x 9 x 5 inches and 4.4 pounds, they're a mite too big and heavy for hand-held operation. For a hand-held binocular that must function well for astronomy and for general viewing, you might consider Nikon's 10-22x50 Action Zooms. For a lower-priced zoom binocular they're surprisingly good, offering reasonably sharp, bright views.
              Q: "Do you supply overseas? (I live in New Zealand?"
              A: Yes, we would be happy to ship a pair of Zhumell 20x80 SuperGiant Astronomical Binoculars to you in New Zealand.
              Q: "Is there a difference in eye relief on the Zhumell 20x80 binoculars?"
              A: We've talked with the Zhumell folks, and they assure us that all the SuperGiants have the same 17mm of eye relief and the same dimensions.
              Q: "I am currently in the the USA and would like to take a pair of these binoculars home for my friend. However, as size is an issue, can you advise of the total package size & weight of this product including case & box etc?"
              A: Including all packing materials, this binocular ships as 8lbs and measures 14L X 10w X 5H.
