Galaxy M74 in Pisces
Note that this is now an old image of M74: an improved version is located here www.flickr.com/photos/mcrowle/10277755896/
Manually, off-axis guided for 5 x 20-minute exposures at ISO 1600, f10.
Unmodified EOS 40D & Celestron C8 telescope.
Registered and stacked using DeepSkyStacker software.
My second subject from Saturday night/Sunday morning. I could do with adding a lot more subs to reduce noise. Also the colour balance is too blue; I have tried to correct this, but there was little red in the subs (except noise) as the camera is unmodified for astrophotography.
