M13 – Great Hercules Cluster

This image was taken Saturday night from my back yard. Celestron C8-SGT with f/6.3 focal reducer. Canon 350D DSLR (unmodified). Guided with PHD through a piggy-backed ST80 using a barlow and my SPC900NC webcam. 16x120s exposures.

Any advice for bringing out (or maintaining) star color? I don’t seem to much star color in my images.

Re: M13 – Great Hercules Cluster

Excellent image Brad. Who needs color when you have depth? There is a hint of blue in some of the fainter stars, which in my opinion is plenty. I've seen images of this great cluster that had too much blue in them. Good work!
