See fits headers for details of exposure times, dates collected, UTC time, pixels size etc. See file meta-data for details of filter wavelength ranges. Files were combined using the free software DeepSkyStacker (DSS): http://deepskystacker.free.fr/english/index.html See DSS tutorial and help pages for how to combine the light-files with the calibrations files. The resulting LRGB master images were then combined using GIMP and various colour stretches to priduce a pleasing image. en 1 10.15125/BATH-01225 https://doi.org/10.1088/1361-6552/acbf1b pub Bath Physics Observatory open Dataset
