Feb13 CN Imaging/Sketching Contest Poll!

We are very pleased and proud to present the February 2013 CCD Imaging Semi-Finalists in the Cloudy Nights Imaging/Sketching Contest.

This image started out as a test under the glorious light dome of Melbourne, Australia. I am located just 15 km (~10 miles) from the CBD of Melbourne. The intent was to focus on debugging, measuring, and recording as much as I could from about my equipment. Well in the end, I learned a lot, and also had seven nights of data to play with.

If you get to see this target at dark sky, it is a real treat. You can see the structure with a fairly modest scope. I have seen it through a 14 inch scope, WOW. It really does look like a giant spider in space.

Great job Terry.
It's nice to see a fellow imager from Melbourne win this.
Dan's image was great too.
