Oh harden up boys and girls
As a astrophotographer we are the first on the field and the last off generally as people are just waking we are stumbling into our beds! I for one brave the winter cold and have seen on my telescope beads of dew frozen! aka its zero or less....... Brilliant seeing mind and so still.
Now i don't mind the summer that i have a cooling capacity of delta -40 deg

so even on the hottest of nights ill be well under zero degrees!
I too am hoping for a cloudless night tonight and in a few weeks time ill sort out a baby oag and FF for the new Megrez 90 so wind or no wind ill always have options!
