This project has its roots in a discussion I had a while back with a
friend who is a keen amateur astronomer. He had been complaining to me
about how he thought that there was a distinct lack of cloud free nights
in our corner of Northern Lincolnshire. In fact, he suggested, the
weather was so poor that it was hardly worth having a telescope at all.
Okay, so maybe that last sentence was a little exaggeration, but his
argument certainly got me thinking - how many clear nights are there in
the year? Being a bit of a skeptic, I am sure that the night sky is
clear on many more nights than my friend suggests.
