It’s mostly standard, star party fare. Rigel Systems Starlites, 9volt. LRI Photon Freedoms, button cell. LRI Photon Proton Pros, aa . And several Sunwayman and JetBeam rotary lights, which combined with color filters are really flexible performers. When Jetbeam discountinued the ring lights ( 2013-2014?) a ebay vendor listed them for $33.33 each :+1: :beer: Myself, members of local astronomy club cleaned him out on the first listing day. The extreme low of the JetBeam frees me from red, courtesy, filtering. I have a red filter for the JetBeams, more because it’s expected behavior, at times, than honest need. Red light conversations are somewhat frequent at astronomy chats, especially since our club has members who are opticians :smiley:
