I've previously been a member of Croydon Astronomical Society (near where I grew up) as well as Observation Secretary for Cambridge Uni Astro Soc. (while a certain Sky At Night presenter was chairman) and I got to use and teach others how to use the 8" Thorrowgood and 12" Northumberland refractors.
While at Cambridge I specialised in astrophysics, doing my 3rd year at the IoA. I've forgotten how to do the maths and a fair bit of the theory since!
