Stunning Look at ISS and Docked Disovery — From the Ground!

This has to be one of the clearest close-up shots of the International Space Station ever taken from the ground! Plus it has the added bonus of having space shuttle Discovery docked to the station. Ted Judah, who lives in northern California captured this image — one of 150 he took during the an ISS pass over his observatory during the recent STS-131 mission. Here’s Ted’s description:

The ISS came into the morning light over the Pacific Ocean just off the coast of northern California and was tracking north-east as it passed directly over my sea-level observatory. I was lucky there was no fog. I have a Canon 30D SLR and Celestron 11″ Schmidt-Cassagrain on an equatorial mount. I track manually and use my precisely-aligned finderscope to aim – when the ISS is in the crosshairs I shoot like crazy. Of the 150 shots I took, less than half have the ISS in frame.

Ted told me he was “stoked” to get such a clear image. Who wouldn’t be?? Nice work, Ted!

Ted is not new to trying to capture the ISS. He won one of “Phil’s Picks” (Bad Astronomer Phil Plait) in Celestron’s “Capture the Universe” contest with another image of the ISS.

Also, Ted has contributed a couple of podcasts to 365 Days of Astronomy, and one of my all-time favorite podcasts is Ted’s description of how he and his family built an observatory out on his father-in-law’s farm.

Here’s another shot Ted took during the same pass:

Thanks Ted, for sharing your wonderful images!

Wow! Astronauts on EVA, As Seen From Earth

Remember when it was a big deal when amateur astronomers starting imaging the International Space Station as seen from Earth, showing individual modules and other parts of the space station? One of the most proficient astrophotographers in that department has now just upped the game: Ralf Vandebergh has captured images of astronauts working outside the ISS during an EVA. Vandebergh, who lives in The Netherlands, used his 10-inch Newtonian backyard telescope to capture an image of STS-119 astronauts Joe Acaba and Steve Swanson working outside the ISS to install equipment on one of the trusses during the second EVA of the mission on March 21, 2009. Vandebergh told me he has been trying to image astronauts working outside the ISS since 2007, but hasn’t been successful until now. “In all opportunities I had until now, the astronauts were not on a visible part of the station,” he said “or they were in shadow or the pass or the seeing was simply not favourable.”

Below, enjoy the video Vandebergh created about his extreme zoom-in handiwork, and his explanation of how he was able to take the images.

Nice job Ralf! Check out his website of other telescopic spacecraft image here.

“It was great luck they were working on the Earth-facing side of the port 3 truss on this spacewalk,” Vandebergh said. “Why? This truss is a reasonable open structure, which means it appears a little bit transparent as seen from the Earth with the black space as a background. This makes this particular truss (and the Starboard 3 truss on the other side) look considerably darker then the other trusses in the vicinity.
When a high reflective white suited spacewalker works in front of this truss, there is a very good
chance you receive light from it on your CCD. By following very precisely the live station camera’s–
and helmet cam recordings on NASA TV, I knew exactly were to expect them on the image.”
