Topic: In search of Degenerates, My Hunt for Sirius-B

Five years ago Dave Chapman and I hunted for Sirius B at an Atlantic Photo Supply public event. After unsuccessfully trying to observe the white dwarf I decided to attempt to image the faint star. My talk is the story of that search using three telescopes over five years. The talk will discuss the difficulties in tracking down this elusive target and some of the techniques used to overcome them.

I’m an electronics technologist with 38 years of design and signal processing experience in the law enforcement, defence and scientific industry sectors. I joined the RASC over 25 years ago and quickly became an avid observer. When I got interested in astrophotography I soon discovered that image processing and image capture were simply two dimensional generalizations of the work I do in my day job.
