The Eskimo Nebula, or NGC2392,
is a bright planetary nebula located in the constellation of Gemini. This
shot was performed on the 12" SCT at f/10 with excellent tracking
throughout the imaging session. Average errors of 0.2 arc-sec on both
axis were typical with virtually all individual data points at 0.5 arc-sec
and less. As a result, all 44 images (2 minutes each) taken were suitable
and utilized for stacking in the final image.
