Finally... a comet pic in the gallery. The top image is a piggyback film image aquired while taking ccd data.


Meade 16in LX200 telescope operating at f/10 and 120mm (piggyback camera)
SBIG ST8E CCD camera with color filter wheel

R G B color production was used to create this image.

Red = 4 minutes binned 2x2
Green = 4 minutes binned 2x2
Blue = 6 minutes binned 2x2

  • For the piggyback film image, the exposure time is around 20 minutes. The comet is centered in the field since that is what the telescope is pointing at. I used Fuji 800 and scanned the negative.
