Atmospheric optics and other daytime phenomena:
Atmospheric Optics Picture of the Day or "OPOD" - including galleries of past images - WOW! whenever sun and clouds are in the sky together, look up! It's more than "just" rainbows!
Atmospheric Optics site with taxonomy of displays by type (rays and shadows, ice crystals, etc.), featuring photos and diagrams of the physics - a terrific reference
Atmospheric Optics page of EPOD (Earth Science Picture of the Day) - more stunning images

History of observatories and telescopes:
Antique Telescope Society - founded in 1991, the ATS focuses on education, preservation, restoration, historical documentation of historic telescopes; it holds an annual convention at an observatory of historic significance in the U.S. or Europe, and publishes the Journal of the Antique Telescope Society (including a special double issue about new primary sources about world-renowned 19th-century telescope-maker Alvan Clark). The ATS has also held periodic regional meetings and, in 2008 in anticipation of the International Year of Astronomy of 2009, one thematic workshop on "The Vintage Observatory: Thriving in the Twenty-First Century" (summary of the ATS thematic workshop's education and outreach sessions appears on the International Astronomical Union website in the October 2010 issue of CAPjournal - see last article). Individual members are skilled at restoring antique astronomical instruments, notably Chris Ray of Ray Museum Studios in Pennsylvania.
