Best brand of 10×50 best binoculars for astronomy with porro prism design?

The truly best binoculars can cost hundreds of dollars. But as far as reasonably priced binoculars go, the Scenix, as others suggested is a good choice. I had a pair for awhile, but now require glasses when viewing, and the eye-relief of the Scenix is too short for eyeglass wearers.

A good pair that work for eyeglass wearers, and are even a little less expensive are Garrett Optical Gemini 10x50 binoculars. I have a pair and am very happy with them.
