About this image

This picture was captured during Thursday evening, between 19:30hrs and 22:30hrs. It is the famous Rosette nebula in Monoceros.

This is  a close up, of a much wider field, that has been taken with a vintage m42 threaded Pentacon 200 mm lens, attached to my modified EOS 1000D.

Stacked in DSS. Then post processed in Star Tools Astro Art and PS CS5. In Adobe I separated out the RGB channels, and saved each one as R - G - B. I then combined these to make a true RGB picture. That had the correct colour balance.

I hope you like the result.

Really impressive image, especially as taken with a DSLR and a camera lens - great stuff.
