whatever could be wrong.
A reknowned (just ask me, i will tell you!) and experienced planetary guru like myself set up last night for a crack at jupiter and mars.
Jupiter looked ok, but cooling system not yet working, so boundary layers made it look shocking!
Anyway, off to bed i says, put the lid over birds fantastic 10" mirror and get up for mars.
So at 5.30am, clear as a bell, i naked eye mars and start trying to find it at 10,000 odd meters of focal length.

hmmmm, this is very hard.... very very hard
So i give up in disgust, pack up laptop in the car so i can go to work and then start to put the scope..... now where did i put that lid?????
arrrrgh, there it is.................still on the bloody top of the tube.............blocking the view!!!!!!!!
