Questar guiding a C9.25

This Questar 3.5 rides guide scope on a Celeston 9.25, with an Imaging Source firewire camera connected to an old Macbook running PHD guiding software. It was much darker than the image makes it appear to be, shot with a Nikon D700 with a Nikon 24mm lens at ISO 5000 for 25 seconds.
I used this setup to shoot the dim planetary nebula M-76.

Nikon D700
