I had to go for one more after being out in the cold for a couple of hours. This is from 5 shots at ISO 1600 of 3.5 minutes duration with the Canon 20da. The scope was used at prime focus of f/4.5.

Good results for only 17min integration.

Good shootin' Jim!! That bucket sure soaks the chip.

Just how cold was it? And you're guiding this manually?

Nice image Jim! Do you use a coma corrector?

No coma corrector is used, the optics have to be perfectly aligned or that is all you see -little comets all over !
