Very cool and profesional grade! The tube of objetive is expandible is a very good feature.
I love the binoculars to astronomy observations and this is one of the better. Very strong construction, waterproof, fogproof, the angle in the eyepieces, the adjust in the eyepiece to eyepiece is easy. They are excellent!
