Photometry

New graph of the contact binary already shot a month ago. This time the minimum of brightness is better visible

This star, in the same field as HAT-P-37 is, to be precise, a binary system consisting of two stars that revolve around a common center of mass, but which are so close that they are in contact. Brightness varies as one of the two stars periodically eclipses the other. These are variables of the type W UMa

Finally a complete exoplanet transit. Something could still be corrected during the shoot, but the result is already more than satisfactory

Graph made with the same images of the one below, but processed with a program written by me.

First serious shooting to hunt for exoplanets. Transit not taken in its entirety due to an automatic PC update. The result was already very promising

First test of shooting an exoplanet. Despite the big uncertainties on the data, this graph made me realize that trying to catch an exoplanet was possible
