I just wanted to let all two of you who read my website know that I’ve just posted a collection of widescreen astronomy photos in my gallery. I downloaded high-resolution photos (some as large as 50 MB) and cropped them down to the same dimensions as my 20″ iMac G5, which is 1.6:1. I got many of them from the Hubblesite and various other websites.
