Image of Optus B3 Geostationary sattelite?

Hi all
Tried my hand at something unusual, imaging geostationary comm sats.
I used Satbuster http://www.satbuster.com/ to get its position from Newcastle, and used the orbital elements from here http://celestrak.com/NORAD/elements/
Then used Star Atlas pro to work out where it is, having to keep updating the map as the earth rotates.
Sat camera with 50mm f1.8 lens on tripod, stopped down to f3.5 then took a 4 min exposure, subtracted a dark, and went over it carefully so as not to confuse hot pixels with geo stationary satellites.

Heres a crop and a downsized full image, with obvious low orbit bright satelite trail
