SkyMaster Pro binoculars are the ideal choice for amateur astronomers or anyone that observes at great distances. Compared to lower-priced large aperture binoculars, SkyMaster Pro uses superior optics, coatings, internal parts and housing materials. With large objective lenses, BaK-4 prisms and fully multi-coated optics utilizing Celestron’s proprietary XLT coating technology, the view through a SkyMaster Pro is second to none at this price point. Massive Objective Lenses - The 80 mm objective lenses have tremendous light gathering capabilities, delivering superior low light performance, even in the dimmest conditions. Choose SkyMaster Pro for use at dusk, dawn and nighttime astronomical viewing. Fully Multi-Coated Optics and BaK-4 Prisms - Every air-to-glass surface is multi-coated with Celestron’s proprietary XLT coating technology. These coatings coupled with BaK-4 prisms increase light transmission through the optical path and deliver crisp, high contrast images with outstanding resolution. Built in Tripod Adapter and RSR “Reflex Sight Ready” Rail - The built in tripod adapter of the SkyMaster Pro 20x80 not only allows the binocular to be attached to a tripod for added stability but it also acts as a balance rail by sliding along the center support rod. A red-dot finder can also be attached to the center support rod utilizing the removable rail. When properly aligned with the binocular, the red-dot finder will allow objects to be brought into view quickly. Lightweight, Waterproof Construction - The polycarbonate and aluminum housing allows the binocular to be lighter weight without sacrificing its durability. The housing with protective rubber armor is extremely rugged and durable with the ability to handle tough use. The fully waterproof housing for use in all weather conditions provides peace of mind when unexpected weather rolls in. The housing is also filled with dry nitrogen gas to prevent the internal lenses from fogging when moving between extreme temperatures or when using the binocular in damp conditions. Enhanced Magnification - Bring distant objects into view with 20x magnification—great for observing celestial objects in greater detail, searching for wildlife in the brush or viewing a distant object on the horizon.

.At 20x Power + 5lbs ... use a Tripod for the Best Enjoyment. ...
I like this binocular so well that I just ordered a 2nd pair of "Celestron 20x80 SkyMaster Pro" binoculars, an "Orion Tritech II Field Tripod with Fluid Pan Head", a "Messier Observer's Planisphere", and a "Guide to the Stars" for my two grand-kids as their 1st Telescope.
On the 1st clear night with these 20x80 binoculars mounted on a tripod, I am able to see Jupiter and clear separation of 4 of its largest moons ... and with two eyes. From what I saw through these binoculars, I would not recommend any more powerful binocular because Jupiter would then more quickly fall out of view ... due to the rotation of the Earth.
Requires firm elbow support to stabilize when holding by hand as these are high magnification.
Mounting adapter works well with tripod or dovetail adapters.
Chromatic aberration noticeable in high contrast daylight viewing.
Light gathering ability good for messier objects

If you're built like the proverbial, they can be used without a tripod for scenic views, yachts and ships etc, but even for a hefty unit like myself, I'm happy giving my arms a rest every now and then, and when I do hold them up I find it useful to tuck my arms in so that my elbows are resting on my torso to create a quasi support frame. Most people I'm sure would be more comfortable with a tripod, especially for astronomy - I use a Hama Star 63, available from all good Amazon outlets near you. Handheld for astronomy with these is a complete no-no - Jupiter simply refuses to stay put and be observed.
Easily focusable, and the tripod mount can be adjusted laterally to get a good balance before tightening everything up.
Build quality is excellent , covers stay put and happy that I could add a separate red dot finder (mounting clip supplied )
Tripod is a must.
Well worth the asking the price.
