La Luna

Having just opened my big mouth in a comment to [livejournal.com profile] bonvogue, I thought I should take a shot at a particular project.

She'd taken a picture of the Moon. I said that perhaps a better tripod would help. That's obvious -- a better tripod always helps. :) Just ask Philip Greenspun.

Still, empiricist that I am, I thought I'd take a whack at it.

Lesson learned: La Luna, la Bella Luna is really small. The picture below is taken at max resolution for my digital camera (3 megapixel), and at max telephoto (6x, roughly the equivalent of a 300mm lens, half of which is electronic gimcrackery inside the camera, and not optical). Result: Yeah, still blurry.

Judge for yerself:




On the other hand, I'll tell you something I didn't expect -- that picture is fast. It's at f13 or so, and 1/125th of a second. La Luna is brighter than you think, too. :)

I'm sure real glass would get better results, but hey, then I couldn't show them to you nearly instantaneously.
