What's the main reason for using binoculars rather than a monocular system? Is it because you get 2x the light without using larger optics? There is a "Binoculars vs Telescopes" table at the bottom of the page, but it doesn't provide any real details. The table appears to be comparing their system with a standard hobby telescope which is larger and bulkier. But I'm wondering why they don't sell half their kit at ~half the price.
Looks really cool. Though the idea of pointing a laser pointer up at the sky always spooks me. Make sure to check for planes on an ADSB website before firing it up.
