Telescope: Skywatcher 8" f/5 Newtonian
Focus: Prime focus
Camera: SAC7B, uncooled
Exposure: 175 x 25s
Date: 8th Sept 2002
Processing: Acquired in Astrovideo as
FITS. Stacked in Iris. Initially RGB, but converted to
One of my first galaxy images. At
that time I was doing log stretching in Iris and struggled with getting a
good transition between the sky background and the very faintest bits of the
galaxy. The sky background itself was not even and that had to be
corrected using a synthetic background made in Iris.
I couldn't get any colour information out
of this image at all, with the technique I was using at that time.
