What the!!
Set the scope up this evening, took some video of Venus. Then did a go to alignment and left the scope just traking on the last cal star. My wife then says "Pizza's ready" (home made , yummy!) I ate my half, came back out to what used to be a completely cloudless sky and whack!!! Full sheet of grey!!!
Only a couple of sucker holes.
Hope the clouds clear out as quick as they rolled in

Or they actually do something like rain all night to help the fire's.
