Lubricate 80mm Espirit focuser.
Rather than learn by my mistakes I thought I would ask for help from those who know what they are doing.
I have only just now woken up having done the 12 till day break shift in the observatory but I did notice the focuser was not nice and smooth on the 80mm Espirit and although I only had a casual look when packing up and really brain dead I could not see how to do anything...
Any tips... I don't want to just spray wd 40 or silicon lubricant around without thinking it thru and armed with reliable advice.
