Now that you mention it Mark, during yesterday I reinstalled the Telrad and the stuff was not there then, I have not looked at the front lens of Finder scope for a long time. It can only mean that it happened at the viewing site last night??. Towards the end of the observing session, around 11 PM, I had difficulty seeing through the Finder,I checked, and there it was, mainly on the Finder lens, the stuff, large blobs of it, 2 - 3 mm in diameter, covering the outside front of the lens. I rubbed off most of it there and then.
But also on the ext side glass on the Telrad.
Thanks for bringing that up.
