TrES-2b lightcurve

TrES-2b on 2019-07-16

This is the very common transit about TrES-2b in Draco, one of the first exoplanet discovered that still one of the most important and observed. We recorded this transit at WBRO-K49 with Giuseppe Marino, Massimo Banfi and Riccardo Papini.
The conditions were good all night long. Just a problem with defocus came after the flip: this changed the initial precision. Without this, we are sure we could reach an RMS down to 1 mmag.

Exposition and setup are always the same: 300 sec with V filter. All calibrations done.

These are the lightcurve and the system reconstruction based on data:
