Primary Mirror cleaning

[hairymunky]

Just had a new bathroom fitted recently, and there was a

hell of a lot of plaser/building dust (builders from hell sort

of stuff). Some of it has found its way onto the primary mirror

of my Lightbridge, and althogh it doesnt "seem" to be

causing any problems, should I "pop" it out and

clean it, or just leave it. Dont want to scratch the primary,

or do any other damage. Just thought Id ask before I plough

on in and end up scoring the mirror or the like...

cheers

See how much you can blow off (clean air obviously) and see how it looks then. Unless its still bad I'd recommend leaving it alone, a little dust has no appreciable effect on the image.

would a can of fresh air oops, I mean compressed air do the

trick, as I have some kicking about that I use for cleaning computer

bits and bobs, I'd be careful not to let any propellant out of the can..

Yep, that would be ideal. Start off at a distance and work your way in until you can see it being effective.
