Comet Hartley in Cassiopeia October 3, 2010
This image is from a Canon D20a with 50mm f/1.8 lens, 15s @ISO 3200.
Camera piggybacked on an FS102 piggybacked on a C14 / CGE mount.
The excessive weight / moment of this setup probably caused the slight image shift.
Below is an enhanced image showing the comet circled in red ...
Comet Holmes taken 2007-Nov-01
Taken with a Canon D20a exposure was 5s @ ISO3200, I believe this was taken through the FS102.
