Is the Celestron SkyMaster 20x80mm Porro Prism Binoculars Worth It? Let’s Find Out
The Celestron SkyMaster 20x80mm Porro Prism Binoculars are a large aperture binocular designed for both astronomical and terrestrial viewing. Celestron promises outstanding performance, especially in low light conditions, thanks to its large 80mm objective lenses and multi-coated optics. These binoculars aim to bridge the gap between powerful magnification and affordability, making them an enticing option for stargazers and long-distance observers on a budget.
As an outdoor and tactical gear specialist, I’m constantly seeking tools that enhance observation and situational awareness. I’ve always appreciated the wider field of view and binocular vision that binoculars provide, versus the often narrow field of view associated with spotting scopes. So, I sought a set of binoculars powerful enough for detailed celestial viewing but versatile enough for daytime terrestrial use.
Upon unboxing, the first thing that struck me was the sheer size and weight. The Celestron SkyMaster 20x80mm Porro Prism Binoculars exude a sense of robustness, though it’s immediately clear they’re not designed for handheld use for extended periods. The rubber armoring feels durable, and the inclusion of a tripod adapter is a welcome sign.
I considered other large aperture binoculars, such as some offerings from Oberwerk and Orion. Ultimately, I chose the Celestron SkyMaster 20x80mm Porro Prism Binoculars for their balance of price, aperture size, and purported optical quality. I hoped Celestron delivered on their promises.
My initial reaction was a mix of excitement and slight apprehension. The magnification power promised impressive detail, but I was wary of potential issues with collimation and image quality, common complaints with binoculars in this price range. Time would tell if these were a worthwhile investment.
Real-World Testing: Putting Celestron SkyMaster 20x80mm Porro Prism Binoculars to the Test
First Use Experience
My initial testing ground was a remote location renowned for its dark skies, about 100 miles from any significant light pollution. I mounted the Celestron SkyMaster 20x80mm Porro Prism Binoculars on a sturdy tripod and turned them towards the night sky. The moon, nearly full, revealed incredible detail of its craters and maria.
During daylight, I used them for long-distance observation across a valley. The image was clear and bright, although atmospheric distortion became noticeable at these high magnifications, particularly on warmer days.
The center focus knob was smooth and responsive, but achieving perfect focus required patience and a steady hand. I immediately noticed the need for very stable support. A decent tripod is non-negotiable with these.
Extended Use & Reliability
After several months of regular use, the Celestron SkyMaster 20x80mm Porro Prism Binoculars have held up reasonably well. The rubber armoring shows some minor scuffs, but the optical components remain pristine. I’ve transported them in their included carrying case, which provides adequate protection.
Cleaning the lenses is straightforward with a microfiber cloth and lens cleaning solution. Collimation remained consistent through my testing. I’ve owned several binoculars in the past, including a pair of Nikon 10x50s, and these Celestron binoculars definitely offer a significant leap in light gathering and detail resolution, especially for celestial objects.
