Portable Constellations
Morning watch, 8 bells (8:16 am)

I’ve had this link for a long time, but have never posted it. NASA has a cool page on how to make constellations in film canisters. Personally, I would add a red LED inside the canister with a small watch battery and mount a switch on the outside so I could project them from each canister. Great for amateur astronomers or for teaching constellations.
