Pictures: Stars and Aurorae

Iridium flare over the dome entrance
First attempts at aurora photography... Couldn't figure out how to set the focus manually, so they're a bit blurry
More auroras
Aurora over MAPO
Aurora over VIPER (for this shot, I had the camera sitting on a mitten in the snow, and my aim wasn't quite right)
Open cluster NGC3766, captured in a random piece of sky
Globular cluster Omega Centauri
