Second image taken with 24mm lens at F2, 1 minute exposure. The lights of Port Lincoln at the bottom right corner.

Wow @ both of those shots. Even following your settings (without tracking though) I could get nothing even remotely like your shots quality. Can't blame the equipment, so must be this photographer (me) simply sucks at comets ;-)

I'd heard 340,000 years. Not sure if that is indeed correct or not though.
