ZWO ASI 1600 pro mono
Exo-planet TrES-3b transit observation.
This is a plot of the brightness of star TrES-3b in the constellation of Hercules (near star Theta Hercules) as the exo-planet passes in front of the star, from our point of view, some of the light is blocked resulting in a slight dimming of the star, in this particular case the star dimmed by about 2%.
These observations are submitted via exoclock project to refine transit data as part of ESA's Aerial space mission.
