I have a telescope (well its actually half a set of binoculars that got damaged) that must have slightly moist air inside it cos its alright when I use it on a sunny day but if I try and use it on a cold night it fogs up slightly on the inside.
Considering the fact that I sometimes use it for stargazing and looking at Jupiter and it's four moons I consider this to be a problem.
It's armoured and waterproof but has a little red screw with a seal on it that I can only figure is for sorting this problem out? Filling with nitrogen?
The little red screw looks like a bleed screw and isn't connectet to anything that it adjusts.
Anyway I figure the best way to get rid of the moist air inside it is to remove said screw, bung the whole thing in a tupperware container with a sachet of silica gel.
Anyone else got any ideas?
