Optical DIY Exoplanet Detector with a DSLR

AI Thread Summary
The discussion highlights the challenges of building a DIY exoplanet detector using a DSLR camera, emphasizing that achieving reliable results is difficult without a telescope due to limited light collection. The author shares personal experience with a CCD camera and telescope setup, noting that even with that equipment, data quality was suboptimal. The article linked provides additional insights, including methods for compensating for atmospheric fluctuations, which were not covered in the video. Overall, the project is recognized as intriguing but technically demanding.

Wow, he's right on the edge of the noise floor. I've done this exact project with a CCD camera and an 8 inch telescope and I can tell you that just using a camera lens without a telescope it's going to be very difficult to see any exoplanet transits. Even with my setup the quality of my data points was lower than I'd have liked. With just a camera you're simply not gathering enough light. (Not to mention how much gets rejected by the bayer array on the camera's sensor)
