DescriptionComet Hartley 2 shot during 45 min period. I wanted to capture it's tail if possible. Because of it's fast motion 30 sec exposures were used, and because of it's low brightness 90 immages have been stacked in DSS to have better signal/noise ratio.
The idea worked and a faint tail stands out pretty nicely.
