Check out this incredible picture of the Great Orion Nebula. It's not from the Hubble Space Telescope. It's the work of amateur astrophotographer Marcus Davies, and it just one of the finalists for this year's Astronomy Photographer of the Year.

When you witness the marvels of the universe that ordinary geeks are able to capture from their back yards, it's enough to keep you up at night... taking your own pics. The finalists in this year's astronomy contest are just mind-blowing. Here are a few more of the finalists, plus a few of the pics from the contest's Flickr pool that we felt should have been on the shortlist! More details about the contest at the link. [Telegraph]

The Great Orion Nebula photographed by Marcus Davies. This amazing image captures the superheated gas and dust of the closest star-forming region to Earth, 1350 light years away. Tons more amazing images at the link.

The Large Magellanic Cloud - Central, by Dave Trimarchi on Flickr.
Mosaic Panels: 3
Exposures per mosaic panel: R:5 hours + Ha:5 hours , B:5 hours + OIII: 5 hours (20 hours per tile, 60 hours total)
Total Field Covered: 240 x 130 arcminutes.


Dates: 12th, 13th, 22nd and 23rd November, 2nd, 3rd, 12th and 13th December 2009.
Location: Gold Coast, Queensland.

Sub-Image calibration and per-filter colour image sigma rejected addition with CCDStack.

Background correction using the PixInsight software's Dynamic Background Extraction Tool.


Green Synthesis, RGB combination, mosaic assembly, levels and Adobe RGB 1998 colourspace conversion with Adobe Photoshop CS4.

This image was an experiment in dealing with light pollution from my site by blending Narrowband filters with RGB and synthesizing Green, usually the most problematic colour.

Using Ha and OIII filters to limit the earthly glows and blending the flat backgrounds from these with standard Red and Blue filters.


For this particular image, being a mosaic, there is approximately 60 hours of exposures here without taking any Green or SII, which would have required another 30 hours of exposures in this case.

In an attempt to limit light pollution influences and also reduce the total amount of time needed to take all the exposures for this three-panel, pseudo RGB image, the Green channel was synthesised from the combined R = R+Ha and B= B+OIII images.
