The gear I’ve ordered has started arriving! We’re going to need some filters for the partial phases.
This is the great Mylar filter material from Thousand Oaks Optical. The one 8×8 sheet is enough to build filters for our Celestron 90GT, binoculars, and a few different camera lenses. The filter material is black on one side (eye side) and silver on the other (sun side). Black should help with internal reflections. The included spectacles are made with the same material.
