Amateur Astronomer Grabs Amazing ISS Picture

Posted by samzenpus on from the good-focus dept.

The Bad Astronomer writes "Ralf Vandebergh is an amateur astronomer, and using a simple telescope with a video camera attached to it, he took an incredibly detailed picture of the International Space Station. You can easily see the recently-installed truss and solar panels, as well as the Space Shuttle Discovery docked to the station."

    Ralf, quite simply, takes amazing photos. From what I understand, these are manually tracked snapshots.

    He has a number of photos posted at Cloudy Nights in the "Planetary and Solar System Observing" forum.

  2. A simple technique taken to an extreme by The+Hooloovoo · · Score: 5, Informative

    He basically used a method reminiscent of a technique used by amateur astronomers to take pictures of planets and asteroids: take a lot of frames using a cheap webcam and stack them together, weeding out the bad ones as you go.

    The principle behind it is pretty simple. When it comes to seeing nearby planets (Pluto and friends are obviously exceptions), telescopes are limited less by magnification and more by atmospheric distortion. What's not clear from the article is if this is a single frame grab (which is pretty cool but not an incredible technical feat) or if he managed to track it precisely enough to stack a few frames.
