Telescope: Skywatcher 8" f/5 Newtonian
Focus: Prime focus
Camera: SAC7B, uncooled
Exposure: 184 x 25s
Date: 4th March 2003
Processing: Acquired in K3CCDTools as
AVI. Stacked in Iris. YRGB image, composited in Photoshop.
Colour enhanced using Multiple Luminance Layering.
The galaxy on the right was much dimmer
than the other two, so its image had a separate histogram stretch done in
Photoshop before being composited back into the man image. I was
pleased that the striking differences in colour in the galaxies showed up.
