This page features some of the telescopes made and work undertaken by the Bolton Astronomical Society trio of Gerald Bramall, Brian Webber and David Ratledge.
Gerald is a self taught machinist specialising in aluminium fabrications.
Brian is ex-British Aerospace and an optics maker of some renown having made tens of mirrors, a 5 inch object glass, a Maksutov and a Springfield mounted Newtonian.
Myself I have been making telescopes for 40 years but still suffer from "aperture fever"!
