The majority of this run was focused on general growth of ice crystals.
image 5-18-11 jagged facets shows an interesting pattern of the pyramidal facet of a growing crystal.
While most of these images are showing the growth of ice crystals, images with temperature -40C or 
higher are ablation images.

General technique was growth of crystals with temperatures at -45C followed by attempting to observe
ablating crystals and then ending the run.
