An FLI Proline 16803 CCD camera with an anti-blooming gate was used to acquire unbinned 10-min exposures through Astrodon H-alpha, red, green and blue filters on an 0.5-m Newtonian Telescope operating at f/3.8


Several cometary globules can be found in the southern hemisphere’s Gum Nebula region, which generally have dense, dusty heads and longer tails that point away from the prominent OB2 stellar association in Vela. Likely originating from ablation of an opaque cloud by the winds and radiation fields from that association’s massive stars, the intricate structure of CG4, shown here, render it as one of the most striking examples. The serendipitous appearance of the nearly edge-on background galaxy PGC 21338, which appears as if about to be devoured by a cosmic predator, is riveting. A tight circlet of stars also appears just to the galaxy's left in this reprocessed RGB image that is H-alpha enhanced.
