IDEA!

  • set timer to 405 seconds, (exp:1/4000s, gain:1023)
  • Aim to take drift scans using all filter
  • speed set to 3, lots of high cloud cover, image observed darkening in the live capture window
  • moved 20 secs in speed 3 to west of sun
  • terrestrial on and sequence timer started
  • drift scan taken with normal filter with lots of cloud (exp:1/4000s, gain:1023)
  • error scan taken at centre with cloud (exp:1/2959s, gain:1023)
  • error scan taken at centre with blue filter with clouds (exp: 1/218, gain:1023)
  • (forgot to change filename prefix however frames are in correct folder)
  • error scan taken at centre with green filter (exp: 1/618, gain:1023)
  • error scan taken at centre with red filter (exp: 1/1477, gain:1023)
  • repeating the error scan with red filter due to concerns of position of the dome (exp:1/1477, gain:1023)
  • despite intermittent cloud, drifts scans to be done to obtain bad data.
  • drift scan taken with red filter with lots of cloud (exp:1/1477s, gain:1023)
  • drift scan taken with red filter with lots of cloud (exp:1/618s, gain:1023)
  • considerable cloud cover (sun no longer visible in parts)
