First Impressions of Celestron SkyMaster Pro ED 20x80mm BAK-4 Porro Prism Binoculars
The Celestron SkyMaster Pro ED 20x80mm BAK-4 Porro Prism Binoculars are a powerhouse of optical engineering, designed for those who demand exceptional clarity and light-gathering capability in their viewing experience. Celestron, a name synonymous with quality optics, has packed these binoculars with features like ED glass, BAK-4 prisms, and XLT coatings, promising stunning views of the night sky or distant landscapes. These binoculars immediately present themselves as a serious piece of equipment for the discerning observer.
I’ve spent years squinting through lesser binoculars, trying to resolve faint galaxies or identify distant wildlife. The promise of ED glass correcting chromatic aberration and the sheer light-gathering prowess of the 80mm objectives is what drew me to these binoculars.
Unboxing the SkyMaster Pro ED, I was immediately struck by their substantial size and weight. The rubber armor felt reassuringly robust, and the overall build quality screamed durability. They felt like they could handle the rigors of outdoor use.
Compared to my older 12×50 binoculars and a friend’s compact 10x42s, the Celestron SkyMaster Pro ED are in a different league altogether. While the smaller binoculars are easier to carry, the SkyMaster Pro ED promises superior optical performance, and that’s what I was after. I chose these over similar offerings from other brands due to Celestron’s reputation for quality and the specific combination of features at this price point.
My first impression was a mix of excitement and slight intimidation. The size and weight suggest serious performance, and I was eager to put them to the test. They seemed like they would truly deliver.
Real-World Testing: Putting Celestron SkyMaster Pro ED 20x80mm BAK-4 Porro Prism Binoculars to the Test
First Use Experience
I tested the Celestron SkyMaster Pro ED during a weekend camping trip in the remote mountains, providing opportunities for both daytime landscape viewing and nighttime stargazing. The weather was initially clear but turned misty in the evening.
During the day, the binoculars provided incredibly sharp and detailed views of distant mountain peaks and wildlife. The ED glass lived up to its promise, virtually eliminating color fringing even in high-contrast situations. As dusk settled and the mist rolled in, the 80mm objectives truly shone, gathering enough light to extend my viewing time considerably.
Initially, the 20x magnification took some getting used to, requiring a very stable platform, which a tripod provided. Focusing was smooth and precise, but I quickly realized the importance of using the included tripod adapter for extended viewing, as hand-holding these binoculars for more than a few minutes resulted in significant arm fatigue.
Extended Use & Reliability
After several months of use, the Celestron SkyMaster Pro ED binoculars have proven to be incredibly reliable and durable. They have accompanied me on multiple hiking trips and several more stargazing outings.
The rubber armor has held up remarkably well, showing only minor scuffs despite being bumped against rocks and trees. Cleaning the lenses is straightforward using a microfiber cloth and lens cleaning solution.
Compared to my previous binoculars, the Celestron SkyMaster Pro ED offers a significantly brighter and sharper image, particularly in low-light conditions. They have exceeded my expectations for both daytime and nighttime viewing, providing a truly immersive and detailed viewing experience.

The field of view is 178 ft at 1000 yards, offering a decent viewing area for scanning landscapes or the night sky. This allows for easier target acquisition and tracking.
Fully multi-coated optics with Celestron’s proprietary XLT coatings maximize light transmission and contrast. These coatings significantly enhance image brightness and clarity.
The close focus distance is 98.4 ft, making them less suitable for observing nearby objects. The design is primarily for long-distance viewing.
