Hey Gun. I can't speak for the Astronomical brand, but I have a pair of Cabelas binos that suit me fine. Just don't ask them to stand behind their product, they won't. I dropped mine out of a treestand and they quite working. I called their "customer service" line and they basically told me I was on my own. All I wanted to know was wear to send them to get fixed, that I would pay to have it done since it was my fault, etc. They told me they don't make them, they just put their name on them. I was literally told that I should have just sent them back and said I didn't like them and they would have sent me a new pair. Honesty doesn't always pay.
