Telescope: Skywatcher 8" f/5 Newtonian
Focus: Prime focus
Camera: SAC7B, uncooled
Exposure: 109 x 30s
Date: 7th Dec 2002
Processing: Acquired in Astrovideo as
FITS. Stacked in Iris. Colour saturation enhanced using Multiple
The colour was not visible at all even in
the stacked image. Only after multiple iterations of colour saturation
enhancement did the variations in colour appear. The balance is a
little too green - evidenced by some green stars.
The longer than usual individual frame
exposures meant a larger number of trailed frames, so I made a sub-selection
of better frames, and used the less trailed stars from that to composite
back into the main image.
