    Note about pictures :
    They were taken in a defocalised mode.
    
    
    Important note : there is another star very near HAT-P-20 : UCAC3 229-88754 other name 2MASS 07273963+2420171. This star is fainter than HAT-P-20 by 1.36 mag (R).
    
    Therefore the Real depth (in flux) is the observed one multiplied by 1.3
