About this product

Model:  cel_skymstr_pro_20x80_72031
Part Number:  72031-CGL

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 utilising Celestron’s proprietary XLT coating technology, the view through a SkyMaster Pro is second to none at this price point.


  • Large 80 mm objective lenses for excellent light gathering in low light conditions or for astronomical observing
  • Ultra sharp focus across the field of view
  • Multi-Coated optics for sharp, clear views
  • Bak-4 Prisms
  • Detachable RSR rail for attaching an optional red dot finderscope
  • Rubber armored for improved ergonomics and protection from every day use in the field 
  • Waterproof and nitrogen purged for use in all weather conditions
  • Extended 17mm of eye relief suitable for eyeglass wearers

Large 80mm 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.

Very pleased in most respects but the eyecups are not very secure. They are OK if you leave them unchanged, but if you wish to fold them back when wearing spectacles and then unflod them when not wearing spectacles they tend to keep coming off.

Jumelle Skymaster Pro 20x80 reçue très rapidement. Absolument rien à dire sur l'emballage, au contraire, si c'était plus souvent le cas comme cela vers d'autres sites, exemple à suivre......... Concernant le matériel, entièrement ravi. Juste quelques essais pour l'instant dans le ciel (nuageux en ce moment chez moi) et sur paysage, le pied, vraiment. Points positifs, netteté, clarté, composants matériels, mise en place sur trépied très facile, utilisation de la jumelle idem, bref, que du bonheur. Point négatif, le poids. Mais c'est vraiment pour mettre un point négatif. Un bon trépied est obligatoire. Sans ça, certains seront sûrement déçus. Pour finir, le prix sur le site est plus qu'intéressant. Après de nombreuses recherches, ils sont particulièrement bien placés. Pour ma part, maintenant que je les connais, j'y reviendrai. Me manque plus qu'un viseur point rouge et en avant........ encore merci FLO.
