When I was down in the Owyhee Canyonlands a few weeks ago, I set up my Canon 70D with 50mm lens and booted up Backyard EOS, a Windows based camera intervalometer that wakes the camera up and executes a planned series of exposures while the photographer is sleeping.. these shots were on a moonlit night, not ideal for long exposures, but I did get some interesting 'light painting' effects on the canyon walls from these long 20 second exposures.

I'm looking forward to getting back out to the desert and doing more astrophotography. My next project is to photograph some deep sky objects with a tracking mount like the Ioptron SkyTracker...

Anyone else into astrophotography ?
