Messier 7 star cluster

Hi all

Here's an image I snuck in before Moonrise lastnight. It's the bright star cluster Messier 7 http://www.skylab.com.au/pmsa/ngc6475.html

The image is 20-minute exposure (4 x 5 min. sub-frames) @ ISO200
with the modified Canon 300D on my observatory mounted
12" f/5 newtonian telescope and autoguided on a G-11 mount with
SBIG 402 CCD camera and 4.5" f/9 newtonian guidescope.

cheers
