This is a 30min exposure on B&W film taken using a specialised and home built
"Cold Camera" on a Celeastron 5 in 1984. The negative was subsequently and kindly amplified
by Dr David Malin in 1986. The amplification process has worked but unfortunately it really
only amplified the faint traces of moistier crystalised on the negative in the -40deg environment
in the vacuum chamber in front of the film. These crystals were't noticable before amplification.
