Ok ... this is probably one of those really basic questions, but this morning when I was out having a look at Saturn I kept seeing what looked like little flies or moths flickering about in the EP ... even though I knew there was nothing inside the tube.
What's that about then?!?!?!!? It really looked like there was some kind of bug inside the tube
Obviously some EP trick of the light/ optical thingo, but what's causing it and can it be fixed?
