I think the improvement would be so minor as to be unnoticeable.

Thanks Mike,
I am only considering this as, having read your article on mirror washing, I am thinking about stripping out my tube and washing my mirrors.
My scope is now about 14 years old and has always had fitted end covers on it plus a dust sheet over the lot, when not in use. My mirror still looks in fare condition, being in an observatory in Broken Hill means that there has never been any dew on it, that is I just don't open up if there is the possibility of dew getting on my optics.
However there is enough dust on it, that I am noticing a fare amount of scatter with my Laser. I use an EZY collimator double pass Laser, their MK II and the scatter caused by the dust on the mirror means that the return beam tends to be spread more than it should. The internal surface of my tube also needs a thorough cleaning to get rid of the build up of dust etc on it. Obviously to clean the internal surface of the tube the mirrors need to be removed.
Being a 16" scope this is not a project to be taken lightly. My remote location means that if I do stuffup and my mirrors need re-coating it is a major hassle to safely transport them the 1000 km to Sydney to get the job done.
If I do strip the tube out then I would have the opportunity to line it and maybe fit some baffles. There is no way that I would consider stripping out the optics just to line the tube or insert baffles.
Regards
Trevor
