Product Details

  • Celestron SkyMaster 18-40x80 Zoom Binocular-side

    Celestron's SkyMaster Series of large aperture binoculars are a phenomenal value for high-performance binoculars. Ideal for astronomical viewing or for terrestrial (land) use, especially over long distances. SkyMaster models feature high-quality BaK-4 prisms and multi-coated optics for enhanced contrast. Celestron has designed and engineered the SkyMaster models to meet the special demands of extended astronomical or terrestrial viewing sessions.

    • Lower magnification allows the user to locate a subject more easily and then zoom in for a close-up view.
    • Multi-coated optics enhances the sharpness of detail and crispness of color.
    • High-quality BaK-4 prisms provide higher light transmission for better viewing in low light conditions.
    • A large objective diameter provides a comfortable viewing aperture at high magnification levels.
    • Long eye relief for more comfortable for all users; essential for those wearing eyeglasses while viewing.
    • Diopter adjustment allows for refinement of image to correct for any differences in strength between your eyes.
    • Tripod adapter included to mount the binocular on a tripod for prolonged viewing sessions or simply for increased stability while observing.

Pretty awesome

I got these as a gift to my dad , which is really hard to get a great gift for , but these did it. Offhand , he can see deer horns out at 400 yard. With a mount this can attach to , I have seen Jupiter's 4 big moons from the city on the sidewalk. Moonlight can be projected onto a paper or child's forehead well enough to see details. The zoom is not as significant as I expected but still useful. The build quality is excellent. The travel case is quality and worth keeping , also the front lens covers are great. 1 complaint is the eyepiece cover is 1 piece that goes over both and doesn't stay on well or block dust very well. Near comically big compared to a normal binocular , as my nephew said "I feel like a goober using this." I highly recommend.

What a handfull

Big pair of binoculars is what I wanted to get and that is why I bought this pair they were around $170 not a bad price compared to other brands. Got them so I could use them out hunting and celestial viewings without having to break out the telescope all the time. They are working well for me. You can hold on to them but I shake sometimes so I would recommend using a tripod that made my observations a lot more enjoyable. I wished I would have got them a few years ago the things I could have seen out in the field in between then and now. Thanks OPT you came through for me again.
