Richard,
Having dealt with optics for some years now and if I owned the scope, I would remove the cell from the scope and very lightly tap around the cell with a rubber mallot to see if this will reset one of the elements which could be the problem from the hard knock. If your very careful, this should do no damage to the glass. You may have to slightly loosen the cell retaining ring first.

I don't even want to guess as to how long a 12" air spaced triplet will take to cool down. Might turn into a fossil first
