SkyMaster Binoculars are economically-priced large aperture offerings from Celestron, great both for astronomy or long range terrestrial observing.  The tripod adapter on the 20x80 model provides support and increased rigidity-indeed, these were never designed to be used handheld.  Take this beast where skies are dark and mount it to a tripod.  Then be awed at their awesome ability to penetrate the inky depths of night, revealing subtle nuances of galaxies and nebulae with all the advantages of using two eyes instead of one.

Multicoated lenses
BaK-4 Porro prisms
Rubber armoring with pebbled prism coverings
Long eye relief combined with large apparent angular field of view

20x80 SkyMaster Binocular is rated 4.4 out of 5 by 49.
Rated 4 out of 5 by from Good, cheap giant binoculars They're giant binoculars. The collect a lot of light and are quite sharp. You can hold them by hand only for large objects and probably not for very long. So mounting them on a tripod is essential, especially for astronomy purposes. Since they do not have angled look through sockets, looking at things high in the sky is uncomfortable as you have to twist your head to be able to look through the tripod mounted binoculars. Lots of people report colimation issues. My pair was fine. For the price (just over $ when I bought them) a bargain. Good for wildlife viewing, but only animals at least 30m away due to minimal focusing distance.

Rated 4 out of 5 by from Good binoculars These are good binocs. The optics are not as sharp as others I own but these are all about power. The first time I pointed them at Jupiter I could see all four of its Galilean moons. I can see brick architectural detail on a Beax Arts hotel tower half a mile away. As others have stated you must use these on a tripod, and the sturdier the better. Because of this it is difficult to view objects in the sky more than 30 degrees above the horizon. If you need something powerful, physically smaller than a telescope, and the ability to view terrestrial objects these are the ticket. Just remember to add the cost of a sturdy tripod because they cannot be used without one.

Rated 5 out of 5 by from Very Good Binoculars for the money. A word of caution, these binoculars tend to be out ofcollimation when you receive them, so it is best to havethem checked in the store or collimate them yourself if youknow how. That said, they are of pretty good quality not topof the line, but for my needs quite suitable. If you arelooking for a good pair of binoculars for the value thesewould be them. Expertise: Amateur Problems Encountered: Collimation is out. Previous Equivalent Item Owned: Celestron 15X70

Rated 5 out of 5 by from Very pleasant suprise I had a pair of Celestron's 15x70 and my eyes took several seconds to see just one image. Other people thought they were just fine. I did like their light gathering power. I saw a lot of good reviews for the 20x80's. So, more or less thinking I'd, probably, have collmination problems, I bought them. What a surprise. They're awesome. No collmination problems. I use them for astronomy. The moons of Jupiter seem to glow. These binoculars are big, but very light. You can hold them for scanning, but at 20 power they're better on a tripod.

Rated 5 out of 5 by from Great! I'm satisfied I bought these for astronomy and they worked great. The first night alone I was able to see the Andromeda Galaxy, Jupiter, Earth's moon, Neptune, the double cluster, Orion's Nebula, and NGC457 an open star cluster. I think the views were outstanding. A tripod is a must with these. They aren't that heavy but I wouldn't want to be holding them all night either.

Rated 5 out of 5 by from Opened up the urban sky So far I have only been able to use these in a VERY urban setting, but last night was clear enough to see quite a bit. The field of view just fits Orion's belt inside to give an idea of what to expect. These binoculars get heavy, so resting them against a window or mounting them to a tripod are necessary for extended viewing. I was able to see the Pleiades last night and was able to pick out a 8.05 magnitude star. I bought these to learn the sky a bit before investing in a telescope and am very satisfied with them so far.

Rated 4 out of 5 by from Optically good, but not very robust. I recently purchased two binoculars - a Nikon 10x25 Trailblazer - something small, light and robust to carry around hiking, and a Celestron 20x80 Skymaster for astronomy use.They arrived promptly, which was good, as I was about to go overseas. Unfortunately I didn't get a chance to have a look at them before I left...The Nikons were fine, but on unpacking the Celestron I found that it wouldn't focus and the eyepieces fell off!Closer examination found that the small brass screw that moves the eyepieces via the focusing rods was broken - it was DOA.I contacted Celestron and they said that I should return it to Celestron in the USA for a replacement. Unfortunately, now being outside of the USA, the postage back will cost more than the binoculars cost in the first place. Having the binoculars repaired or replaced means I'll be waiting until I return in about six months. In the meantime I've done a temporary repair and they are useable if I'm careful.Apart from that problem I think the binoculars are very good value for money. Optically they are quite good. Some other reviewers have complained about the general low-quality of the finish and they are not very robust, but for about $bucks, what do you expect? Yes, the little Nikons I bought are much better quality, both optically and mechanically, but they are also in a different class. If you want robust 80 mm binoculars, then get some Steiner or Kowa etc binoculars. But then you are paying 10 to 20 times as much.Some people have also complained about the poor collimation of the Celestron Skymasters, but if you search the Internet you can find information telling you how to easily re-collimate them.They are designed to be mounted on a tripod, and I think they would be much easier to use if they had a 45 degree angled eyepiece, but of course this would add a lot to the cost!Overall I think these are value-for-money, but they are just a bit fragile - make sure you treat them carefully. The little Nikons will are thrown in my backpack. The Celestrons will be going in a hard carry-case.

Rated 5 out of 5 by from Thanks Bunches I purchased these binoculars for some amatuer star gazing. They have been absolutely stellar. After mounting to my camera tripod they have been splendid tools for sighting.The binoculars are surprisingly light for thier size and have been equally as fun and useful for sighting during the daylight hours.The lense caps tend to fall off to easliy and the carry bag could be a little more robust with better clasps.With that said though I bought the Binoculars for sighting not carrying and I had always intended to mount them to a tripod.The supplied neck strap is decent anyway so even off the mount they transport pretty well despite thier size....and they are Huge ,quite a little conversation piece...I reccomend Moon viewing with these for sure ,absolutely stunning.
