Celestron Cometron 7×50 Binoculars Review

Using binoculars over basic telescopes holds many advantages. The lightweight design makes them portable. Just grab your favorite pair and head out the door. Telescopes usually observe smaller amounts of entire sky. Binoculars provide a broader field of view, helpful for viewing galaxies or star clusters. The small, compact size of binoculars makes them ideal for long viewing sessions. The Celestron cometron 7×50 binoculars provides great value for the price.


The Celestron cometron offers affordability and decent visual performance. Multicoated lenses reduce glare and provide a clear field of vision. Optical ability serves both stargazing and land-based viewing. The 7×50 magnifies objects from a relative distance away. Collimation of each barrel is quick and straightforward. Several minutes is all it takes to focus each lens. Light and durable, the Celestron cometron easily holds up on the field. A carrying case and strap comes included, making transportation easier. Large exit pupils increase the amount of light reaching the eyes. As a result, night time viewing becomes possible. They also allow eyes to adjust faster in dim lighting. Most face shapes fit the Celestron cometron 7×50 comfortably. The center focus wheel controls the spread of both barrels. Water-resistant material withstands moderate levels of moisture. The lightweight also allows one to use the Celestron cometron for long periods.


The Celestron cometron 7×50 offers little image stability.  Stability plays a crucial part in stargazing and planet observing. A tripod and adaptor fix this problem. Failure to collimate each barrel renders the binoculars unusable. The focusing module is sensitive and easily knocked out of alignment. Another issue revolves around the optical power. The 7×50 magnification does magnify objects a distance away. However, do not expect to see fine details. The lenses fog up with moderate levels of humidity. No additional information comes included. Beginners will want to buy an astronomy field guide. All levels of light pollution have a strong impact on viewing quality. Ambient light makes dimly lit objects hard to see. Lens caps possess no retainer cord. As a result, they are easily misplaced.

First-time buyers should consider investing in the Celestron cometron 7×50 binoculars. The price, handling, and added accessories complete the package. The optics provide enough power to view larger celestial objects. However, the 7×50 optics fall short compared to telescopes. Those wanting something with more optical power should consider a telescope. The wide field of view easily showcases galaxies and other star clusters. Fine details like craters or moons are unable to be seen. No additional information comes included. Anyone starting out will want to invest in a start chart or field guide. Overall, a great tool for beginners interested in backyard astronomy.
