Thanks Steve for the very nice observing report. The Leupold Olympic 10x50 is one binocular I have wanted. Very light wt. for a 50mm binocular. I don't think I have ever read anything about using this binocular for astronomical observing. If I remember right Walter ngc6475 was going to buy one of these and did get one on Ebay but the binocular had mud etc. on it and wasn't as described so he sent it back.
