My Andromeda Strain
Saturday, November 5, 2016
I strained hard to find the galaxy Andromeda (M31) in my camera's viewfinder, and I strained to get a good sharp focus. Using a 70-300mm lens zoomed all the in, the galaxy appears in the upper left portion of the top image. A successful focus was achieved by focusing to infinity in manual, then tweaking it back just a bit. The image, captured from Brentwood Drive NE in Cedar Rapids, Iowa at 9:05 pm CDT, Friday, November 4, 2016, is a 6 second exposure at f/5.6, 5000 ISO and 300mm focal length. Andromeda was shining at apparent magnitude 4.5 and was 70 degrees above the horizon.
