There is nothing like viewing celestial objects through a pair of large aperture binoculars. Objects take on a 3-D effect. Especially noticeable are large nebulas and clusters. And when it comes to viewing comets there is nothing better than a pair of Vixen BT80M binoculars. With the ability to interchange eyepieces, you have the opportunity to view everything from wide field star cluster to high power viewing of globular clusters or large galaxies. It’s your choice!
