• QHY178C Coldmos - Darks by varying the gain at different temperatures

  Par astrokraken dans QHYCCD QHY178C/M Coldmos le 26 Juillet 2023 à 22:01

  QHY178C Coldmos typical specification is : Gain = 1 Offset = 200 This page shows darks taken at different values of gain and temeprature, for 60s exposure and offset=200. The aim is to evaluate the value that the gain shouldn't exceed.

   

  Each dark : 5 images, Offset = 200

  Exposure : 60s, Temperature = 0°C

  Gain=0	Gain=5	Gain=10
  Gain=15	Gain=20	Gain=25
  Gain=30	Gain=35	Gain=40

  Result : Gain should not exceed 35

   

  Exposure : 60s, Temperature = -5°C

  Gain=0	Gain=5	Gain=10
  Gain=15	Gain=20	Gain=25
  Gain=30	Gain=35	Gain=40

  Result : Gain should not exceed 35

   

  Exposure : 60s, Temperature = -10°C

  Gain=0	Gain=5	Gain=10
  Gain=15	Gain=20	Gain=25
  Gain=30	Gain=35	Gain=40

  Result : Gain should not exceed 35

  Conclusion : From 0°C to -10°C, Gain should not exceed 35 when Offset = 200
