Required Equipment

Required Equipment

The two initial workshops that will enable Mountaineers to be certified for dark sky trips to Trips to Goldendale Sky Village for observational astronomy will require red light FOBs, Planispheres, and some instructor created content. These materials will be provided to students as part of the enrollment in the series.

Binoculars, laser pointers, telescopes, mounts, filters, and eyepieces will be used and their care taught during the workshops. These materials will be provided to the workshops, but are not to be kept by students. Students may bring their own gear from this list for use in the workshops, so long as the gear intended to be brought is approved of by the instructor ahead of time.
