90 Millimeter Observatory


About Us

The 90 Millimeter Observatory encourages learning the night sky through naked eye, binocular and small telescope observation in an effort to educate the public about astronomy and the effects of light pollution. Join us on our adventure exploring the cosmos with small telescopes ranging in size from 90mm (3.5 inch) to 150mm (6 inch) and astrophotography using a DSLR camera. We invite and encourge people from around the world to join us.
