Vanguard Ocean 7x50 Full-size Waterproof Binoculars

Like MOST marine binoculars these are individual eye focus. This works great for astronomy because you are looking at far away objects. Once you focus, you never have to focus again. Crystal clear images. No fogging. A bit heavy, but wow, what a view....

The paperwork included in this package shows a center distance focus. It says to focus left eye, then right eye and then use center knob to focus for distance. There Is not center knob to focus.

It's useful on my boat, but please note that you have to focus each eyepiece SEPARATELY. Otherwise, works well.

Received for fathers day. Never had a telescope before although I have thought about getting one. Really clear with 3/4 moon giving some dramatic shadows around the craters. Saw a planet that appeared to have two rings around it. Don't know enough...
