Night of October 29-30, with the lights of the fair a half mile away and deteriorating
transparency. A composite of 15, 60 and 120 second exposures. (Trapezium detail
from photos taken through C9.25 a few years ago.) Taken with a 300mm f/4L (non-IS)
recently bought specifically for astro work. I'm pleased. Modded 40D with CLS clip filter.
