  Poznámka:

  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
  Location : C2PU/Calern Observatory (IAU_010), France [long.: +6.92277, lat.: +43.75377, alt. 1260 m]
  Telescope: Epsilon, Focal length 9.36m, Aperture diameter: 1.04m

  Science camera: QSI 632, temp.: -20°
  
  
  Weather: 
  1st image: temp.: 2.6° (dome+outside), pressure: 864 mbar/hPa, wind: 4.4m/s, hum.: 62%

  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
