About Our Telescope
Thanks to a generous donation we received in 2018, we equipped our 14-inch Celestron telescope with a computerized mount on the Skydeck. The Paramount MX+ mount allows us to go to objects near and far with the push of a button. Once there, it will track the object as it moves across the sky throughout the night.
