It is my fault.
Last Wednesday I bought some astronomy binoculars, (they are huge and really powerfull) and it has rained since!
I reckon I have had about an hours use out of them, last wed night/thurs morning at around 0230 it was clear for a bit. Has been cloudy and rainy since.
I should send them back, you watch then the sun will come out and clouds disapear.......
