  • Dress warm. Night time can get chilly with a light breeze.

  • White lights can be used around the visitor center & parking lot. Avoid pointing a white light including car headlights at the observatory.

  • Red lights only adjacent and inside the observatory. This protects your dark adaptation and gives you a much better eyepiece view.

  • Please take your time at the eyepiece. The human eye does not work well in the dark. Ask for an assist if you can't see anything thru the eyepiece.

  • If you have any questions please share. We have quite a few friendly volunteers with a breadth of knowledge and experience.

  • Jupiter & its 4 largest moons

  • M51, Whirlpool Galaxy, 2 galaxies colliding

  • M97, Owl Nebula, a planetary nebula

  • M81, Bode's Galaxy in the Big Dipper

  • M65-M66, a pair of galaxies in an eyepiece view

  • M1, Crab Nebula, supernova remnant
