Sorry to hear about your Skies Dave
I am lucky enough to have clear skies here in Gove tonight.
The transparency is good, but the seeing only average.
Due in part to patchy high cloud I think, reducing the limiting magnitude.
Still .. managed a good look at M42
Could not easily see some other clusters to the north though.(M36,37,38)
Heres hoping tomorrow night is even better with a dark site trip planned with a few of the local lads.
Time for Bed !
