DOBSONIAN OPTICS
An authorative and easy to read website on the subject of optics relating to astronomy is:
http://www.oldham-optical.co.uk
They are an optical supply company based in Scarborough in the north of England; established since the mid eighties. Their website is constantly being improved, has recent additions and an excellent section on Cassegrain collimation.
Good diagrams and a lot of thought behind the accompanying text raise this site above the rest.
Go see and then start craving for aperture.
