Four-Years Ago (31-July-2011) — New Jersey

Backyard Summer Nighttime Sky Over New Jersey.

Star Trails taken by three cameras. (1) Looking North: Nikon D3s camera and 24 mm f/1.4 lens (ISO 400, 24 mm, f/4, 30 sec). (2) Looking South: Nikon D3 camera and 24 mm f/3.5 PC-E lens (ISO 400, 24 mm, f/4, 30 sec). (3) Looking South and Up: Nikon D3x camera and 14-24 mm f/2.8 lens (ISO 400, 14 mm, f/4, 30 sec). One hour composite star trail images. Dew settled on the 14-24 mm lens making the center of the image darker and making it look like there are few stars.

Seven-Years Ago (31-July-2008) — Colorado

Summer Nighttime Sky Over Colorado.

Star trails from my room at the Marriott Residence Inn in Boulder, Colorado. Composite of 180 images taken with a Nikon D3 camera and 24 mm f/3.5 PC-E lens (ISO 200, 24 mm, f/5.6, 30 sec exposures). Raw images processed with Capture One Pro 8, and combined using Photoshop CC 2014 (scripts, statistics, maximum). Note that these images were taken using the in-camera intervalometer and noise reduction so for every minute, only 30 seconds of exposure. I’ve learned how to do it better since then — using an external intervalometer and doing the noise reduction post processing.
