Spiral galaxy NGC 2903 is only some 20 million light-years distant in the constellation Leo. One of the brighter galaxies visible from the northern hemisphere, it is surprisingly missing from Charles Messier's famous catalog of celestial sights. This image was taken February 27 and 28 and March 1 and 3, 2011, and consists of 10.5 hours of total exposure. The imaging session was under the control of CCDAutoPilot.
