Obligatory shot of just the moon

Image

Yup, it's the moon. I included this to document the exposure. Getting the moon right is tricky, since it's a small but bright object in the middle of a dark background. Anything with auto-exposure is going to mess this up, unless you have a very long lens so that the moon fills much of the frame.

This picture was one of a series of exposure tests. The brightest parts of the moon were near, but not past, the top end of the sensor range. The parameters were:

ISO 200, f/8.0, 1/125 second

5 Mar 2010 at 19:24, Groton Massachusetts, 300 mm lens, full frame (36 x 24 mm) sensor, cropped result.

See also https://en.wikipedia.org/wiki/Looney_11_rule which puts the exposure within 20% of this.
