Who the Cometron 7x50 suits
The calculated exit pupil of 7.1 mm gathers plenty of light for dim skies, and the under $100 maker list price band keeps the cost low. Porro prisms and tripod adaptability make it a fit for fixed sky watching.
At 27.3 oz it is lighter than the 36.8 oz median, yet 13 mm of eye relief is short for glasses, and the body is water resistant, not waterproof.
