Notes
Estimated to lie about 12 million light years from Earth and span nearly 60,000 light years across, NGC 253 is one of our closest and brightest neighbors outside the Local Group of galaxies. The rich dust lanes and delicate HII regions of this object along with its large apparent size make it a particular favorite of astro-imagers. From the pristine skies of Las Campanas, Chile this object transits less than 4° from the zenith, making it a desirable object to image from that southerly latitude.

Total exposure time was 21 hours 30 minutes. This image is the result of a collaborative effort between Howard Hedlund of Astro-Physics, Inc. and Dave Jurasevich.
