GJ 1214 Transit

June 21th, This session was aimed at the first exoplanet detected by the MEarth project. The parent star is a red dwarf and the planet is a super Earth with 6.55 Earth mass.

It's a difficult target because of the magnitude of the star V 14.67. I decide to use a Blue Blocking filter to have higher transmission and keep the signal at a reasonable level.
