How To Detect an Exoplanet Using Just a Canon Rebel XS

To detect planets orbiting around other stars you do not need an enormous telescope or equipment that will break your bank. You can do it using a Canon Rebel XS, a cheap telephoto lens, and a barn door tracker, i.e. something that helps with the tracking of the stars.

On IEEE Spectrum, David Schneider describes how he did it. The grounding idea is to apply the transit detection technique. In other words: you can use an ordinary DSLR to detect stars that become less bright during the time their planets are passing between the star and the point of observation (that’s you and your camera).

What’s the barn door tracker? To do what David Schneider did, you need a device (where you’ll mount the camera on) that can compensate for the rotation of the earth. Without this device, you would picture star trails instead of a sharp snapshot.

Using a Canon Rebel XS (around $200 on Amazon or eBay, a manual-focus Nikon 300mm telephoto lens (around $100 on eBay), a Nikon to Canon adapter (around $15 on Amazon), and the mentioned self-made tracking device, Schneider framed HD 189733, a star with known exoplanets that orbit the star every 2.2 days. In order to detect the transit of the planet, Schneider shot 50 seconds exposures for 3 hours. The transit of the planet lasted 108 minutes.

Says Schneider:

The hardest part of the whole project proved to be waiting for an opportunity to observe the transit of HD 189733’s exoplanet, which takes place once every 2.2 days. That sounds frequent, but transits that occur during daytime or are too close to the horizon are impossible to observe. […]  And of course, I needed clear skies.

Finally, after weeks of waiting, an opportunity came in mid-October. I recorded images for almost 3 hours, beginning about a half-hour before the start of the 108-minute transit. That, I figured, would capture the transition from normal brightness to ever-so-slightly dimmed and back to normal again.

Obviously you can’t see the transit just by looking at the pictures. You have to do some computing stuff. Using the free astronomical image processing software Iris and then MS Excel, Schneider made

[…] differential-photometry calculations—that is, comparing HD 189733 with one of […] four reference stars to compensate for changes in atmospheric conditions. The scatter in the final results was about the same size as the signal I was attempting to measure, but the general dip in brightness was easy enough to discern nevertheless. The average magnitude of the target star diminished and recovered just as the exoplanet’s transit began and ended.

The video on top is where David Schneider explains the process, and shows how he did it. definitely impressive and cool stuff! You can read more about it here at IEEE Spectrum, where Schneider details all aspects of the process.

Yongnuo Cloned Another Canon 50mm Lens (the Nifty-Fifty)

Yongnuo

After having cloned the Canon EF 50mm f/1.4 lens, Yongnuo did the same game with the EF 50mm f/1.8 II lens (the Nifty-Fifty), one of Canon’s best selling budget lenses.

The Yongnuo YN50mm F1.8 lens looks very similar to Canon’s EF 50mm f/1.8 II. It’s already available on Amazon and eBay for less than half the original’s price, which is $125 on Amazon. You can get the EF 50mm f/1.8 II replica for around $50. Too early to say if the Yongnuo can hold up to the original.

  • Angle Range: Diagonal 46° /Vertical 27° /Level 40°
  • Lens structure:5 groups 6 slices
  • Minimum aperture: f/22 /Filter diameter/Number of available:52mm/1
  • Closest focusing distance: 0.45 meter
  • Maximum magnification and field of view:0.15×160×240mm (when located to 0.45 meter)
