I'm an optics geek, and have made about ten telescopes, as well as used too many binoculars to count. So here are a few thoughts:

Power is over rated. It's really hard to hold anything over about 8x still without propping yourself against a rock or tree. 10x is enough to give some people motion sickness.

Aperture is heavy. If you're hoping to get great big lenses to study the nighttime sky, your shoulders and hips will resent it. 50mm is going to be heavy, even 35mm rewuires a traditional structure that weighs more. My 125mm sky glasses weigh over five pounds.

Optical quality won't matter until you need it. Cheap Binoculars seem fine in a store. The best test is to take that outside at night and look at a bright star. If it resolves to a tiny dot when everything is focused, you're good to go. If it shows flare, won't focus completely, or resolves to a large dot, you'll have to decide if you need better quality.

When I take binoculars backpacking I use a pair of Pentax 6x25 or so...quite small and relatively light. They cost about $100 or so on sale.

But I usually don't carry binoculars any more on the trail, since I don't need the extra ounces, and rarely use the things o. The trail.

YMMV.
