Celestron Cometron 7×50 binoculars review

As a first binocular for young astronomers, the Celestron Cometron 7×50 binoculars excel. As a grab ‘n’ go, “don’t really care if they get trashed,” second set of binoculars for adults, the Cometrons are without equal.

Cometron 7×50 Key Specs:

Magnification: 7x
Objective lens diameter: 50mm
Angular field of view: 6.8 degrees
Eye relief: 13mm
Weight: 1 lb, 11 oz

The Cometron 7×50 and its big sister, the 12x70s, appeared in July 2013, 10 months after the discovery of Comet ISON, which was predicted to graze the sun on Nov. 28, 2013. Had ISON survived its close-up with our star, it might have made for spectacular viewing during the holiday season. The Cometron name, a solid marketing idea, would have been fortuitous. But, alas, Comet ISON never became large enough to see very well through Cometrons. It was ripped apart by titanic gravitational forces a few hours before it even reached its closest encounter with the sun (‘perihelion’).
