You won't believe how incredibly filthy your corrector (or Newtonian mirror) can get before it starts to cause you issue.

You're right Peter, where I live in the Blue Mountains has its drawbacks at times. Wood fires, apart from the smell and bronchial problems, definitely causes problems with the optics over a period (so much for living up here in the clean fresh air) and thought it was wonderful. I used to run a wood fire until natural gas became available but curse them now, somewhat analagous to a reformed christian or smoker. If you want to get a real shock, put your scope under a eucalypt/gum tree after a night's viewing and see what lands on your objective lens/corrector plate (especially if they are brand new)
