Data Log

Used Autosave Sequence located Desktop/Data/20131016_RC/25darks60s.seq

(Forces file name change compared to last log book)


20 x Dark frame per temp per exposure time

NN denotes image number

Temperature (deg C) Exposure time File name
-05.0 0.1, 1.0, 5, 10, 60, 180 eg T-05.0_NNN_E0001
-07.5 0.1, 1.0, 5, 10, 60, 180 eg T-05.0_NNN_E0001

Activity Log

  • Took off cover for telescope & Camera, no water from last nights down pour
  • Turned on Camera and followed steps detailed here
  • Set temperature to -5 deg C, waited 30 - 40 mins for stable temperature
  • Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
    • Autosave feature allows running of each permutation whilst saving automatically
  • Data files have a different file name type than 16/10/13 due to the autosave feature, now in format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
    • File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
  • Submitted Data obtained to Dark Log Book 23/10/13 as a record for files
  • Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
  • Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
  • Submitted Data obtained to Dark Log Book 23/10/13 as a record for files
  • For data analysis will need to change Dark Log Book 16/10/13 file names so that they match that of the autosaves output files for easy file name reading.
