Only recently, in the last 30 years, has there been conclusive evidence of the existence of planets outside our Solar System (often called exoplanets). The most straightforward method for detecting them is to observe a periodic dimming of the host star as the planet orbits in front of it.
Is it possible to spot an exoplanet from home, with a telescope and a camera? I took hundreds of photos of a star to extract it's brightness change over time and find out if any dimming can be seen.
