The past two days I was out at Harvard Forest to help collect samples for Morgan, a PhD student in the lab. I know the skies at Harvard Forest can be pretty dark so in addition to working boots I packed my camera and tripod. The result of some patience and an hour of post-processing can be seen below. In the picture’s top left you see the Coathanger or Brocchi’s cluster. At bottom right Sagittarius and the galaxy’s center sets into trees lining Prospect Hill road. On the bottom the Torrey Labs (left) and the Fisher house (right) and the trees on Prospect Hill road are lit up by street lights. The final picture is a stacked exposure of 10 shots at 25 sec. each with a 12mm / f2 lens at ISO 6400. (click for a full sized version)
Another PhenoCam gem! Half Dome rises almost 3000m above sea level at the eastern end of the Yosemite national park. The western side lights up in the evening sun. That’s a lot of magnificent granite in the evening sun. Recently Google documented the ascent of another famous rockface in Yosemite, El Capitan, using their street view project. It makes for a good read and some sweaty palms if you are not so comfortable with heights.

I just got the first images from the multispectral raspberry pi. I currently have two cameras running on the camera multiplexer. One standard RGB pi camera and one NoIR pi camera with a blue rosco filter.
