Love it or loathe it, launching a sports car into space is a hell of a spectacle, and did a great job at focusing the spotlight on the Falcon Heavy spacecraft. This led [Rogelio] to wonder – would it be possible to snap a photo of Starman from Earth?
[Rogelio] isn’t new to the astrophotography game, possessing a capable twin-telescope rig with star tracking capabilities and chilled CCDs for reducing noise in low-light conditions. Identifying the location of the Tesla Roadster was made easier thanks to NASA JPL tracking the object and providing ephemeris data.
Imaging the Roadster took some commitment – from [Rogelio]’s chosen shooting location, it would only be visible between 3AM and 5:30AM. Initial attempts were unsuccessful, but after staying up all night, giving up wasn’t an option. A return visit days later was similarly hopeless, and scuppered by cloud cover.
It was only after significant analysis that the problem became clear – when calculating the ephemeris of the object on NASA’s website, [Rogelio] had used the standard coordinates instead of the actual imaging location. This created enough error and meant they were looking at the wrong spot. Thanks to the wide field of view of the telescopes, however, after further analysis – Starman was captured, not just in still, but in video!
[Rogelio]’s work is a great example of practical astronomy, and if you’re keen to get involved, why not consider building your own star tracking rig? Video after the break.
