What I Like About The Celestron SkyMaster 20×80 Binoculars

Packaging & Accessories

Right out of the box, I was impressed with the sleek Celestron-branded carry case included with the SkyMaster 20x80s.

The plush interior padding gives me peace of mind that my binocular lenses will remain protected.

I also appreciate the detachable objective lens caps which add an extra layer of security during transport and storage.

General Quality, Design & Build

At first glance, the sizable objective lenses are apparent – a key feature I was looking for in my next set of astronomy binoculars.

The 80mm lenses allow increased light transmission, resulting in brighter and clearer images.

Despite their larger size, the binoculars still maintain a sophisticated, durable feel. The rubber armor coating gives a comfortable, non-slip grip that has proven useful during long observation sessions.


After many nights of putting the Celestron SkyMaster 20x80s to the test, I can confidently say their performance has exceeded my expectations.

Terrestrially, they deliver impressive magnification for viewing birds, insects, and other wildlife.

The crisp focus allows me to pick out fine details even at great distances.

Astronomically, these binoculars have let me explore Saturn’s rings, Jupiter’s moons, and various star clusters from my urban backyard.

I’ve even been able to faintly make out the Apollo lunar landing site craters – an exciting feat with a portable pair of binoculars.

Tripod Compatibility

Given the increased weight that comes with the 80mm objective lenses, I was pleased to find these binoculars work wonderfully with a tripod.

The included tripod adapter screws in securely, allowing smooth pan and tilt movement.

I like having the tripod option for longer celestial viewing sessions as it helps reduce shake and fatigue.

Who Are The Celestron SkyMaster 20×80 Binoculars Best For?

Based on my experiences, I would recommend the Celestron SkyMaster 20x80s for:

  • Amateur astronomers seeking an affordable alternative to bulky telescopes. The powerful 20x magnification opens up clear night sky views without the hassle of setup.
  • Urban astronomers like myself who need enhanced light transmission to cut through light pollution.
  • Versatile nature enthusiasts who want one quality pair of binoculars for both terrestrial and astronomical viewing.
  • Eyeglass wearers who will appreciate the long, adjustable eye relief which allows clear observation while wearing glasses.
  • Beginners just getting started in astronomy looking for an easy-to-use, cost-effective option.

Final Verdict: Should You Buy The SkyMaster 20×80 Binoculars?

For those searching for a durable, high-performing pair of binoculars suitable for both astronomical and daytime use, look no further than the Celestron SkyMaster 20x80s.

The unmatched blend of powerful magnification, crisp focusing and tripod compatibility has made these my go-to optical instrument.

I highly recommend them to fellow hobbyist astronomers and nature lovers alike.

When it comes to getting your hands on them, without doubt the best place to do so is on Amazon. You’ll benefit from speedy delivery and more often than not, the best price.
