Question by R & H: Best astronomy binoculars under 0?
At least 50mm of aperture, no more than 60mm due to heaviness (will be hand held and compliment an 8" Dob). Anywhere from 7-10 magnification.
I'm interested in the Senix line from Orion which is right at $ 100

Answer by Geoff G
I'd recommend the Orion Scenix 10x50. These have been highly rated by both Phil Harrington and Robert Thompson, two people whose opinion I trust.

Question by Chosen One: What are the zoom on these astronomy binoculars?
I have seen binoculars that say 12-100x 70 and they needed a tripod but it wasn't big enough to have the big tripod adapter in the middle. I was told that 12-100x was their magnification and 70 was the diameter of their objective lenses in millimeters but when i see 20 x 80 binoculars they have a 80mm objective lens but is 20x there only magnification, these are bigger than the 12-100x 70 ones i saw. what does 20 x 80 really mean and how could the smaller ones have more zoom?

The zoom part is in the eyepiece. The general size of a binoculars is closely related to the diameter of the objective lenses. So, Yx80 binoculars are larger than Yx70 binoculars, no matter what the power (Y).
Zoom on binoculars is not so good because the zoom feature requires more lenses, and more lenses mean a darker image. 100x is too much for binoculars anyway. After about 20x a 80mm lens binoculars does not offer any more visual information.
I strongly suggest avoiding any zoom binoculars.
