Summary[edit]

Description

Noisy!

$25 eBay lens, diaphragm stuck wide open.

Many of the fainter "stars" in this image are just hot pixels and quantum noise. Check out the previous image in my photostream for a stacked, low noise version of this starfield.

Nikon D600 DSLR on tripod Vivitar 135mm f/2.8 manual focus F-mount lens, set to infinity stop and shot wide open. ISO 12,800 and 2 second exposure to minimize star trailing while capturing some fainter stars.

Shot in Big Valley, California, on a concrete slab next to our largest hot tub. Big Valley has dark skies, and plays host to the Golden State Star Party (GSSP) each year, about three miles from our Ranch.
