What Makes Celestron SkyMaster Pro ED 20x80mm Porro Prism, – 1 out of 2 models Stand Out?
The Celestron SkyMaster Pro ED 20x80mm Porro Prism, a binocular designed for serious observation, immediately signals its intent with its imposing size and promise of exceptional clarity. Celestron, a name synonymous with quality optics, aims to deliver a superior viewing experience with this model, specifically targeting astronomy enthusiasts and those requiring high-magnification observation at long distances. The inclusion of ED (Extra-low Dispersion) glass, large 80mm objective lenses, and fully multi-coated optics are standout features suggesting a commitment to image quality, setting it apart from more basic binocular options. The SkyMaster Pro ED hopes to be a benchmark for brightness and clarity.
My journey to the Celestron SkyMaster Pro ED was driven by a desire to elevate my stargazing experience. My smaller 10×42 binoculars were simply not cutting it when trying to resolve faint deep-sky objects or the intricate details of the lunar surface. I needed a binocular that could gather more light and provide sharper images, and the promise of ED glass to minimize chromatic aberration was particularly appealing.
Unboxing the SkyMaster Pro ED was impressive. The binoculars feel substantial and well-built, with a reassuring weight that suggests quality components. The rubber armor provides a comfortable and secure grip, and the overall design appears robust enough to withstand regular use in the field.
I considered the Orion GiantView ED 20×80 binoculars and the Oberwerk BT-82XL-ED as alternatives. Ultimately, I chose the Celestron SkyMaster Pro ED due to Celestron’s reputation, the availability of 1.25″ filter threads, and the balance compensation rail. The others lacked at least one key feature.
My first impression was excitement tempered with a bit of intimidation. The size and weight are definitely noticeable, but the clarity of the view even in daylight was remarkable. I was eager to test them under the night sky.
Real-World Testing: Putting Celestron SkyMaster Pro ED 20x80mm Porro Prism, – 1 out of 2 models to the Test
First Use Experience
My first real test of the Celestron SkyMaster Pro ED 20x80mm was during a camping trip to a dark sky location in the Mojave Desert. The skies were clear, and the seeing conditions were excellent. I mounted the binoculars on a sturdy tripod and began scanning the Milky Way.
The performance was breathtaking. The large 80mm objective lenses gathered an impressive amount of light, revealing countless stars and faint nebulosity that were invisible to the naked eye. The ED glass did an excellent job of controlling chromatic aberration, providing sharp, high-contrast images with minimal color fringing around bright objects.
Using such a large binocular definitely took some getting used to. Finding and tracking objects at 20x magnification required a steady hand and a well-balanced tripod. Initially, collimation felt slightly off, but this was easily corrected.
Extended Use & Reliability
After several months of regular use, the Celestron SkyMaster Pro ED 20x80mm has proven to be a reliable and impressive performer. The binoculars have held up well to being transported in my gear bag, with no signs of significant wear and tear on the rubber armor or optical components.
Durability has been good so far. I’ve used them in temperatures ranging from freezing nights to hot desert days, and they have consistently delivered excellent image quality. The rubber armor has protected them from minor bumps and scrapes.
Cleaning the lenses is relatively easy with a microfiber cloth and lens cleaning solution. The overall maintenance has been minimal.
Compared to my smaller binoculars, the SkyMaster Pro ED provides a significantly brighter and more detailed view, especially of faint deep-sky objects. It has exceeded my expectations in terms of light-gathering ability and image clarity.
