Description

The ZIP-package contains:

  • Canon RAW (CR2) and DCRAW pre-processed (PGM) pictures of the sky with the green laser switched on/off, elevations 10 and 20 degrees
  • Calibration data for Canon EOS 6D Mark II + Fish-Eye lens EF8-16mm at 8mm (wignetting, geometrical distortion)
  • C/C++ software 'green_laser.cpp' for extracting the data from the pictures (incl. Windows-executable). Version 2 has improved median filtering and built-in correction if the laser beam does not go exactly overhead. 
  • Detailed description of the software and the method of taking and processing the RAW pictures in PDF format
  • Extracted data in EXCEL workbooks
