I mounted my EOS 6D and 24mm lens on a sky tracker to follow a section of sky for 7 hours during the long night of the December 2014 Geminid Meteor shower. The radiant of this shower, the point to which all the Geminid meteors appear to trace back, is just to the right of Castor and Pollux, the two brightest stars in the constellation Gemini in the upper left corner.
With the wide angle lens, I was able to frame the shot to include a section of the Milky Way, and below that the beautiful winter constellation of Orion, the Hunter.
Using an intervalometer, i shot 25 sec exposures (with a gap or 4 sec to download) through the night. Then I was able to lay back in my lawn chair (in my down jacket and down bibs as the desert temperature outside Death Valley dropped to 40 F) and enjoy the shower. (And not even get wet!)
Tracked 25 sec exposures, filter-modified EOS 6D, Rokinon 24mm f/1.4 lens at f/2, ISO 4000. A total of 40 exposures were combined in Photoshop CC as individual layers with Lighten blending. The full Photoshop file totals 4.2 GB and spans 7 hours.
