A bit heavy, but very clear.

I bought these binoculars for my wife to view the moon and the planets. The overall quality and how clear the lenses are great for the price. The binoculars are heavy and require a good tripod to enjoy the power of these binoculars. A camera tripod is too light duty, buy the offered Celestron tripod.

Perfect beginners' astronomy binoculars

I love these binoculars and wrote a review of them on the Skies & Scopes website here:

Binocular Review

These binoculars are extremely heavy. It’s almost impossible to look through them for more than a minute and actually be still - your arm starts to shake. We have a tripod and that helps but the tripod limits your flexibility of easy movements.

big binoculars

For the money these are a great buy.

Customer review

I have to say before I got the box open I had the same feeling as when I got my 16 Lightbridge that feeling was kind of like... these are a little bit bigger than I thought it would be. I paid a little extra for shipping so they would be here today this paid off in more than one way. #1 clouds are rolling in as I type this, #2 our club had our weekly star party at a local park. So I took these and left the telescopes at home. Binocular First Light! I set the 20x80s up on my very best tripod a & I took a stool along. I arrived at the park just after sunset and just before moon set. Because the moon was about to disappear behind trees first light was on the thin lined moon. I have to say I was impressed with the view. These binoculars really rock the moon! The view was excellent and sharp. Next, I set my sights on Jupiter. I could see the 4 moons and Jupiter. I was a little disappointed in the amount of color distortion on Jupiter itself...I got some red on the side of it. I happened to set up next to another astronomer, who using the Skymaster 11x70's I called him over to take a look. We compared we agreed the image in my 20x80 was clearer than the 11x70's. Needless to say the image wasn't that bad and it acceptable in my book as I didn't buy these to use for planetary work. Then I moved to M31. This was a really nice sight even in the light pollution of San Antonio, TX. I could clearly make out the galaxy & I was totally impressed with the image I got. It was 142% better than my 10x50 Celestron Close Up Binoculars. I sat there a long time just staring. I searched around Cassiopeia for a while and then I landed at NGC457. Nice. Then I moved on to the double cluster and that was really nice. At this point in the night I started to really think my purchase had paid off. Soon the Pleiades (M45 were high enough to see with the binoculars. These 20x binoculars provided and eye filling view of these 7 sisters. I thought I'd better get a wider set of binoculars like some 11x80's but I think that 20x is nice. I'm still close enough to see things in detail but still wide enough to take in a lot of the sky.I chatted with folks for a while. People came and took a look though the binoculars and they were all impressed. Neptune was above Jupiter and just above 3 stars in a line. I decided to star-hop with the 20x80. I started out on Jupiter moved to Nashira ***** eye visible star above and to the left (south of Jupiter, then to Deneb Algedi which was above and to the left (South of Nashira. From Deneb Algedi I simply panned to the West to find a line of 3 starts. (I really like lines of stars as the are easy to confirm your in the right place!. Above this line I could see a blueish little Star that became more visible with adverted vision as there was a lot of light pollution. That was Neptune! The line of stars I saw were (45 Cap, 44 Cap, and 44 Cap. Now Orion's Nebula was at a point in the sky where I could get a look, but some thin clouds started to roll in. I set up the tripod and binoculars and took a quick peak before heading in to write this. I was treated with the nebulosity in the Nebula which was a nice sight despite the thin rolling clouds. After a quick look at the red star Betelgeuse I headed in and the clouds did the same! These binoculars will round of my observing equipment quite nicely. I have a set of 10x50s, 12x50s and now 20x80s. I have various telescope ranging from a 60mm refractor to a 16 dobsonian. I feel that these would make a great addition to a well rounded astronomer or a beginner, they are absolutely great.

Great optics

I bought these to use on a Couch Potato Telescope chair. I had previously used a set of Orion Scenix 10x50 on the chair and was pleased. This binocular beats the pants off that smaller pair. The weight is reasonable for the mounting and is easily supported by the CPT system. I found the image to be stable and easily adjusted. I like the fact that the focus adjustment is stiff. That allows me to set it for my eyes and optical infinity. My binocular does not wander in focus once I set it. I wear glasses, and the field of view is quite impressive. One of the objects I looked at my first night out in dark sky was M31. I have used a number of different telescopes in viewing M31, but I have never appreciated the huge extent of M31 like I did when I first looked through the binocular at this galaxy. It was huge! It extended several degrees from the center of the field in both directions. The two neighboring galaxies, M32 and 110 were also quite obvious. I call my new binocular The Eyes of Texas and plan to run the Astronomical League deep sky binocular list a second time with this bigger binocular. I can not wait to get to the Texas Star Party and run John Wagoner's Binocular List from ****! It should be a lot of fun.
