Col became interested in Astronomy while still at high school, but spent most of his career exploring the Geology of NSW. For about 6 years he wangled a job with the University of NSW, looking after their new Automated Patrol Telescope at Siding Spring. Shortly after that he retired to a farm near Bathurst and built an observatory in the paddock. From there he continues to undertake CCD photometry of Asteroids and (when he has time) variable stars.
