David's Images of the Day Photoblog
There was a partial Lunar Eclipse while I was working at the Merck/Sirna site in Boulder. The sky was clear and I spent much of the night observing the eclipse from the Sirna parking lot. At one point I must have stood in front of the camera for a selfie.
Mississippi River Headwaters. The only place you can cross the Mississippi River by foot. Itasca State Park. I did this as a kid many, many years ago and ended up with several leeches on my legs. Images taken with a Nikon D200 camera and 18-75 mm kit lens.

While harvesting some carrots from my Grow Tower garden several very large grasshoppers jumped out. This one is almost 2 inches long.
Daily Electric Energy Used (39.2 kWh) from Sense and Daily Solar Electric Energy Produced (42.9 kWh) from SolSystems and Locus Energy. Still cool outside but more clouds for a net surplus of 3.7 kWh.

Star and jet trails plus clouds. Images taken with a Nikon D810a camera and 14-24 mm f/2.8 lens (ISO 200, 14 mm, f/4, 120 sec). Raw images processed with Capture One Pro, and the composite generated with Photoshop CC (statistics, maximum). One problem I continue to have is moisture condensing on the lens as temperature cool over the night. Especially with wide angle lenses with lots of glass surface area. You can see how the condensation blurs things in the final image. I’ve read about adding electrical resistance thermal tape to heat the lens, but worry about damage and optical artifacts. I’ve also added a time-lapse video of the night sky show.
Star trails looking north and the waxing gibbous moon (both a composite and time-lapse video).
