High Magnification HD Professional Zoom Binoculars 10-380X100 Telescope High Power 10-30X Binoculars for Bird Watching

Very sharp view throughout magnification range, good value and power of 10 to 30 magnification seems accurate. Useable for astronomy, but it does have color fringes around the moon, but shows creators well . I was not expecting apo glass, that would cost 10 or 20 times more. They weigh about 3 pounds and are hard to hold steady at 30 power, I needed to rest my elbows on something or use a tripod. A simple L shape connector will connect these binoculars to most tripods. The lenses covers are effective but not connected and the carrying case is minimal. Overall I am pleased with these binoculars, I plan view the green comet showing now and try cellphone photography.

I love these binoculars! They are exactly as described. I was able to try them out for a bit in my yard as soon as they were delivered before it got dark. They are very powerful. The price was also very reasonable for such quality! I would definitely recommend this item!

These were bought with astronomy and birdwatching in mind. I have some familiarity with optics and had noted these have two components of better instruments, namely BAK 4 prisims and fully coated optics. They are surprisingly sharp and bright for the pricepoint. They should be mounted, for the most part, but there is one major glitch. The mounting orifice was not tapped deeply enough to secure to a tripod. Unless you have a quarter/20 tap to deepen it, you will need to search around for the right washers, which has worked for me but is a nuisance. These binoculars have the typical narrow field of zooms, yet are really quite sharp even at higher power. Decent optics.

I used these twice to see the full moons, and what an amazing view. I love studying astronomy as a hobby

Fair product for its price.Too bulky, the zoom is big, but can't really see much once it is zoomed in.I would buy again for BEACH, NATURE lookout, it is nice, but there are other better choices out there.

The zoom was a bit clunky, stiff, not as good as I hoped, but the rest of the binoculars were phenomenal. I would definitely buy another pair because they work well.

It took me 4 tries to find this more powerful unit. I upgraded from a 7x50 unit but learned not to get anything less than a BAK4 type reflector lens setup. The bonus is the zoom capability which takes several tries to wrap you head around understanding that the zoom lowers the field of view which is what makes this unit good for planetary and moon observation. Definitely military grade look and feel.

Perfecto todo
