Using your telescope in the city can be frustrating with all the stray light all over the place. You can’t do much about the skyglow, but you can shield yourself from stray light sources nearby.
Rather than buying a pre-made shelter for hundreds of dollars, you can build one for about a hundred dollars. Jeremy Bingham will demonstrate in his talk how he did just that with a lot of PVC, some found wood, and a bunch of felt.

Enter lithium polymer batteries, rare earth magnets, miniaturized solid state inverters, 2.4 GHz spread spectrum frequency hopping transmitters and receivers.

Watch Dan explain how you can get off the ground for a single Benjamin.
