Binocular astronomy using the Sky Window

I love to observe the night sky with binoculars. I use a 7x50 Bresser and a 15x80 Vixen together with the Sky Window, a binocular mirror mount. If you want to know why I like binocular observing, especially in combination with a binocular mirror mount, just go to Sky Window and Binoculars page. It has has been completely rewritten. A lot of images and useful links have been added as well. Enjoy!
