Here is a shot of the Globular Star Cluster in Hercules known as Messier Object 13 (M13). This picture was taken with a canon 500mm F4.0 lens with a 2X teleconverter to get a 1000mm focal length at F 8.0. The ISO was set to 1600 in a full frame Canon DSLR. The final image was made by stacking 8, 2 minute exposures. The freeware program Deep Sky Stacker 64 was used to stack the images. The final processing was done with the canon software "Digital Photo Professional" that came with the camera to crop the image to get the cluster centered better in the frame. Note: the dim elongated smudge of light in the upper right of the photo. This smudge of light is a spiral galaxy known as NGC 6207 and is approximately 30 million light years away.

What did you use the track? Excellent photo.
The camera and 500mm lens (1000mm with the teleconverter) where piggy backed on a 5 inch APO refractor that was mounted on a Losmandy G11 mount. I used a Starlight Xpress Lodestar X2 inserted at the prime focus of the Refractor and connected to a laptop running the PHD software for guiding.
