fantastic graham - you even got the leaping cheetah, and can just about make out the donkey.
So, there was a pig, a cheetah, and a donkey....sounds like that start of a good joke!

Can anyone finish it for me?
Having my cleanout, I came across the bahtinov mask for that scope. Its no good to me anymore, so I will try to get it in the post for you. It really does make focusing a whole lot easier.
Cheers
