Astronomical observations can be made with these binoculars. They have a large 70mm lens that gathers in lots of light which is why they can be used in dim light conditions. There is a detachable RSR rail for attaching an optional red dot finder scope. They have a rubber casing which makes them easier to handle and will provide protection from bumps and scratches as well. It is waterproof and also has nitrogen inside which will stop it from steaming up, so great for use in all weathers. There are two size options with a 15 x 70 and a 20 x 80 available to choose from.
