  Circumstances: 
  Those data were acquired during the practical phase of an Astronomy course delivered by the Côte d’Azur University (Diplôme Universitaire d’Astronomie Observationelle (https://www.oca.eu/fr/duao-oca#:~:text=Le%20DUAO%20(Dipl%C3%B4me%20Universitaire%20d,th%C3%A9orique%20et%20pratique%20en%20astronomie)
  
  
  Data acquisition:
  Date: Sunday, January 15th 2023, 1st image 18:56; 84th and last image: 21:55

  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
