Celestron 20x70 SkyMaster Binoculars are extremely impressive for viewing landscapes, seascapes, wildlife and grand buildings but they can also double up as astronomical binoculars to let you see the nearer celestial objects in the night sky when the large aperture of the 70-mm objective lens will fully come into its own.

The high-quality BaK-4 prism glass and multi-coated optics will enhanced the contrast of the view for better contrast in the images for a clearer appreciation of what you are looking at.

An adapter is included that means you can mount the binoculars on a tripod for extended and steady viewing without your arms tiring.
