Celestron Skymaster 20x80 Details

Designed with astronomy in mind, these Celestron Skymaster binoculars also make a good choice for long range terrestrial observation. At 80mm in diameter, the two objective lenses act like large windows in that they are able to capture and then let in more light than smaller ones. This in combination with a fully multi-coated optical system helps them deliver a bright and high-quality view. With a 4mm exit-pupil, they are also a more than capable instrument in low light conditions.
The very powerful 20x magnification helps you see further into space and observe objects that are simply not visible at lower powers, or it provides you with a more detailed view of objects nearer to earth. For example views of the moon are simply stunning using this instrument.
A downside to the higher power is that you get a reduced field of view making it a little harder to locate objects and often means that it is impossible to enjoy something like a constellation of stars without having to move the view about. If this is a concern to you then perhaps consider one of the many lower magnification binoculars within the Celestron Skymaster series. The built-in tripod adapter makes it easier than ever to fix this binocular to a tripod to achieve a rock-steady view of something to gain the best possible image detail and that is easy to share with others. Whilst easily enough for most users, the amount of eye-relief maybe just a little short for many users of eye-wear. In these cases, it may be better to opt for a slightly lower powered instrument like the 15x70 Skymaster for example.

About Celestron SkyMaster Binoculars

Award winning SkyMaster series by Celestron offers one of the best binoculars for astronomical and terrestrial viewing. Extreme power and large objective lenses offer incredible view-through with extreme detail in the most challenging light conditions. With SkyMaster binoculars, you are able to observe stars, planets, comets, galaxies and more. The smallest in the series with SkyMaster 8x56 configuration received the Space.com's 2014 Editor's award for being the best medium astronomy binocular and SkyMaster 25x100 as the best astronomy binoculars. There are also two zoom version available to be able to change magnifications without moving the position. The binoculars have Porro prism system with multi-coatings on glass surfaces (except DX models which are fully multi-coated) and are splash-proof and enclosed in rubber armoring for protection.

Basic Features

The SkyMaster binoculars are one of the most powerful binoculars on the market offering models with 15x, 20x and 25x magnifications combined with large objective lenses, from 56mm to 100mm. This configuration allows you to use them in poorest lighting conditions in the wildlife and for astronomy applications. Two of the models also offer variable magnifications, so you can get finer details without moving the position. They are made out of aluminum housing enclosed in rubber armouring for maximal protection against impacts and abrasions. The rubber armoring is also rugged to prevent any sudden slips. The pocket sized binoculars have a roof prism design to make them more compact and light, and bigger models have a Porro prism system to make them brighter. The binoculars are splash-proof, tightly sealed to not get damaged when using them in the damp areas.

Optical Properties

SkyMasters are equipped with high-quality BaK-4 prisms for better light transmission and multi-coated lenses to help not only with brightness, but also to enhance the contrast and colors. This also helps to prevent the chromatic aberration, glaring and internal reflections. The smallest pocket sized models are fully-multi coated to help provide better images since they are using less bright roof prism system. All the models offer central focusing mechanism with grippy wheel that allows you to make quick adjustments with the help of right-eye diopter. Eyecups are foldable, but offer very generous eye-relief, and you can make it perfect even for eyeglass wearers.

Accessories

SkyMaster binoculars comes in case for storage and protection and binocular strap. They are also equipped with objective lens covers and eyecups covers to protect the lenses, but are not included in smaller roof prism models.
