What did you use to capture that image? Nice pic indeed.
Thanks all. Sorry for the late reply. I used a Canon XSi with a 55-250mm lens. Aperture f/11, shutter 1/125, ISO 100, manual focus. Used mirror lockup and IR remote. Here's a post processed version. I'll run some of the .raw files through Lightroom and post a few.

I was in a prime viewing location for the eclipse. I was at work, but luckily I was able to take a break and go outside to see it. Here are a few of the pictures taken by friends:
I think that red one will be my new wallpaper!

EuropasOcean_KPHand003crop.jpg




Explanation: How much of Jupiter's moon Europa is made of water? A lot, actually. Based on the Galileo probe data acquired during its exploration of the Jovian system from 1995 to 2003, Europa possesses a deep, global ocean of liquid water beneath a layer of surface ice. The subsurface ocean plus ice layer could range from 80 to 170 kilometers in average depth. Adopting an estimate of 100 kilometers depth, if all the water on Europa were gathered into a ball it would have a radius of 877 kilometers. To scale, this intriguing illustration compares that hypothetical ball of all the water on Europa to the size of Europa itself (left) - and similarly to all the water on planet Earth. With a volume 2-3 times the volume of water in Earth's oceans, the global ocean on Europa holds out a tantalizing destination in the search for extraterrestrial life in our solar system.

So... who all is going to try and catch the transit of Venus tomorrow? ;)
As long as its not cloudy, like it has been for the last 2 evenings, I'll be trying to catch it. Will have to go the projection route since I wasn't able to find any solar filters in time :(

<Raises hand> (y) I'm borrowing a welding hood. How 'bout you?
I have Baader film and some homemade lens caps that I'll use. I would love to find some #14 welders glass but I can't seem to find anyone online that sells just the glass and the goggles are rather pricey. Baader works just fine and is actually rated for optics so I know it's safe to use on my phone and dslr.

Edit: apparently I didn't look hard enough :) http://goo.gl/exOae

Edit 2: sweet... if anyone is interested: http://goo.gl/5hHt6 for the goggles and http://goo.gl/exOae for the 50mm round glass (x2)

Great shot.
Thanks! I really need to get some better optics. That dip in the top right of the photo (which in reality is bottom left) is from a very very very small dent in the lens tube that I didn't think would cause any problems after I accidentally dropped it on concrete haha
