Last night wasn't great - there seemed to be a lot of high, wispy stuff.

I think you're right, was almost like a fog. Very damp all round too. Thanks for your take on things. Must invest in a star atlas.
Here's an interesting page with one guy's ideas of Telrad placement and even a custom dew shield (with pictures
).
