Eclipse? Opportunity for photographers to show off
May 24, 2012Some photographers have the patience and skills to show off well. Found this picture of last week’s eclipse, by Mark Langridge, on TwitPic:

Mr. Langridge provided details; he used a Celestron telescope with his Nikon camera:
Celestron CGEM 800 HD, Canon EOS 60Da, Kendrick Astro baadar solar filter.
Blow this image up, or go to Langridge’s TwitPic site and see it in its large format, glorious detail. You can see the mountains on the Moon . . .
