Hunt for TrES-3b exoplanet transit

Nights in June are very short in central Europe – not even three hours. Fortunately the TrES3-b exoplanet minimum lasts only about hour and on the June, 5th I managed to record the minimum. The exoplanet traversed between the star and us and it caused the very small star brightness reduction – about 0.02 magnitude, that is near the limit of detection of my setup. But, eventually, exoplanet transit has been recorded:

Gears used: TS130/910 refractor with 0.79x reducer, Atik383 mono camera with Baader L filter, EQ6 mount, OAG guided. Single exposure – 120 seconds.
So – exoplanet detected from the backyard – yay !
 
Clear skies!
