Celestron SkyMaster Binoculars

Celestron is better known for its telescope line, however the Celestron SkyMaster series of binoculars are among the most affordable.

I have owned a Celestron Super C8 since 1985. Recently I removed the tube from the original Byers Worm Gear driven forks and mounted onto a computerized German Equatorial mount. Enough about telescopes for now. Let's look at Celestron binoculars.

My neighbor Larry across the street from me owns a set of Celestron SkyMaster Giant 15x70 Binoculars. Now Larry is a character. He uses his astronomy binoculars to spy on the police helicopters (a.k.a "ghetto birds") that fly over the neighborhoods at night.

Now our neighborhood is not in a crime ridden area of the city but we are in an older part of town not far from the airport every so often it can get interesting with the occasional police chase on the nearby I-405 freeway.

One evening Larry's cousin Rubin who is also a fellow amateur astronomer came over with some of his smaller gear and from the street we were doing observations of Jupiter and the Galilean Moons. When we showed Larry Jupiter through his second-hand Celestron binoculars he was even more amazed.

We started making viewing comparisons with our binoculars and thankfully my very expensive 11x80 Parks binoculars won. But Larry's Celestron SkyMaster binoculars were really good. We stood out in the street looking through our binoculars long enough to attract the attention of our neighborhood policeman Officer Rios. He got into the act with his police issued binoculars but our binoculars still outperformed his observing Jupiter.

So the Celestron SkyMaster 15x70 Binoculars are a spectacular value for the size and ability of the binoculars themselves. Let's run the numbers:

  • 4.4° degree view of the sky (230 feet @ 1000 yards)
  • 4.7 mm exit pupil
  • 3 lbs (1.360 kg)
  • Water/fog resistant

The Celestron SkyMaster 15x70 Binoculars are the most affordable set of binoculars on the market. So much so in fact I bought a set on Amazon myself. The Celestron SkyMaster 15x70 retail for $119, but on Amazon it is much less and a terrific value. This set of binoculars is also one of the most highly reviewed by other amateur astronomers alike. I will be using these when I go overseas when I travel. I figure at least If they are stolen it is not like I am out hundreds or even thousands of dollars. I can't say that about my 11x80 Parks.

Celestron has a line of SkyMaster binoculars with zoom capabilities. Zoom on a set of binoculars is a total waste of money. Using zoom will greatly reduce the exit pupil thus you lose the already faint light of a celestial object out of existence.

Avoid the Celestron SkyMaster 20x80 Binoculars and Celestron SkyMaster 25x70 Binoculars for astronomy. Both simply have exit pupil sizes too small for astronomy and better suited for day light uses.


The largest of the Celestron SkyMaster group is the Celestron Skymaster 25x100 Binoculars. These binoculars are so large that you cannot hold them up for very long at all. The 25x magnification factor makes it humanly impossible to hold them steady. They are very, very heavy! You need a very sturdy tripod to support them.

The Celestron Skymaster 25x100 Binoculars are also incredibly inexpensive at under $300. Other amateur astronomers have had great success using them to locate a number of Messier and Herschel objects. Expect to pay at least the same amount for a camera tripod to support this beast of a binocular!

Anything over 10x magnification factor requires a sturdy tripod to hold any set of giant binoculars steady while observing.

Celestron offers their Celestron Heavy-Duty Altazimuth Tripod that will allow you to mount any of the SkyMaster binoculars.

What makes their tripod different is that it has the fine tuning controls for making the altazimuth adjustments as objects in the sky travel East to West across the sky. You can read more about tripods in the Tripod section of this site.
