Eta Carina by Dylan O'Donnell

Dylan is the System Administrator from our ISP, Dragnet. This lovely image taken through the BVR filter set, was the first ever attempt of using an astronomical CCD camera by Dylan.  3 x 30 second exposures with Red, Green and Blue filters combined in Photoshop using channels. Levels adjusted slightly to balance histogram.http://www.gco.org.au/st8/
