June Meeting follow up

Many thanks to Simon White from the Eddington Astronomical Society, who gave an excellent talk last month on the science and maths behind telescope optics. The talk started by explaining the basics of telescope optics and went on to explore topics such as resolving power and minimum and maximum magnification. I think beginners and experienced telescope users were left with some food for thought.

Simon has passed on a couple of slide with the key formulae he used as well as some links to further information for those who are interested.

Randy Culp’s original material is at www.rocketmime.com/astronomy/Telescope/telescope_eqn.html

A pretty comprehensive coverage of the subject is at www.telescope-optics.net  - not for the faint hearted!

Simon's astrophotography adventures are constantly updated at www.simoninthelakes.co.uk

I'm sure we will all be interested to here from Simon at future CAS meetings.
