Yes Krishan, humidity hit 100pc early on with water dripping everywhere.
The cloud got me at 9.15pm as I was starting on the Moon, it seemed to come from nowhere thick and fast for the rest of the night on 19th.
I use an hand made EVA foam dew shield over 14" Newtonian which seems effective in delaying mirror misting but it won't work forever - gives me 2-3 more hours.
Thanks for comments, John.
