Amateur Astronomer Grabs Amazing ISS Picture 80

Posted by samzenpus 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 [cloudynights.com] in the "Planetary and Solar System Observing" forum.

    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 [wildimaging.co.uk] 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.

      Stacking frames does not require precision tracking. You only need to track it well enough to keep it in the frame. And in some cases partially out of the frame still has limited usefulness. The software correlates the positions based on what is in the picture. If there's enough of a pattern to make the alignment (at sub-pixel resolution), then it's easy. If it's fuzzy, you might have to do the alignment manually.

      • since the angular speed and direction of the ISS an other orbital objects is constant and known, do you even need fancy alignment correlation?

        If you have precise timing for your shots, would it suffice to align the first and last picture, and the alignment of the rest can be infered from them?

      ...take a lot of frames using a cheap webcam [wildimaging.co.uk] and stack them together, weeding out the bad ones as you go.

      You might be interested to have a look at some software called ALE [dyndns.org], which can be used to do this more or less automatically; you give it a sequence of frames and it'll synthesize a superresolution image combing data from every frame.

      (You can also use it to generate panoramic images from video pans --- it automatically locates, rotates and transforms every frame correctly, figuring everything out for itself!)

      The only problem with it is that it's really slow, so you'll probably want as big a computer as you can humanly manage.

      One day I should try taking some simple digital camera footage of the moon and running it through ALE just to see what happens...

      Honest to the Force, my friend's daughter was taught by her mom to decern the Space Station from the Moon, "that's no moon, thats a space station". So when she went away, her daughter (3 years old) grabbed her dad, pulled him to the bedroom and pointed at the space station, and said "No Moon, Space Station."

        Even though its on the other side, facing away from us.

        They can lift the print of the guy who screwed it on too.

        But the real feat is that they can make out the license plate of the car across the street of a suspected terrorist by enhancing the reflection on one of the space stations windows, on a cloudy day.

        I used to enjoy TV. Its almost sad. I can watch a rerun of something like "Columbo" and I find fewer plot holes and more credible police work, more credible set designs, more credible ... everything, than I do on CSI. Sure in Columbo the villain was usually improbably or even implausibly ratting himself out... but compared to the routine violation the current limits of technology, and in many cases the known limits of even theoretical sciencce we are subjected to in the CSI's... Columbo is actually the more beleivable... by far.

    I mean I wouldn't be surprised if he was getting pretty close to that limit. http://en.wikipedia.org/wiki/Rayleigh_criterion#Explanation [wikipedia.org] To make that short I kind of remember this from my physics class that ultimately the limit on being able to differentiate between 2 objects depends on the size of your main mirror/lens and the wavelength of light you use. (IE a bigger main mirror or shorter wave length of light means you can differentiate between closer and closer objects.) If I remember correctly I did the math and found out that you'd need a mirror about 250 meters across to resolve the landing site on the moon from an earth based telescope. (But I can't remember if that resolution was 1 meter or 30.)

A couple of weeks into working on things, someone from higher headquarters said they were concerned about including information on how high the satellites are above the Earth.

    This is obviously a fake. If you look closely, you can see the wires holding up the space station! The only rational conclusion is that the space station was filmed in front of a live studio audience under strict NDA. Quick! Somebody notify Fox News! They'll do one of their award winning exposes.
