Hi Anthony
Welcome to IIS and the world of astronomy. Binos' are a great way to introduce yourself to the night sky and as a minimum I would recommend something like 10 X 50mm but you can go up to 100mm. Anything over 70mm need to be mounted on a tripod or some other type of mount and even the humble 50mm perform better when mounted, the steadiness helps to see fainter objects more easily.
Personally I would go for 15 X 70s' or 20 X 80s' and a tripod as you will be able to see a wide range of nebula, star clusters and the moons of Jupiter , most retailers of telescopes carry a range of binoculars and there is online shops as well with a price range from $50 to $1000 depending on your budget.
Clear Skies
Jeff
