Another thing I've thought of is to mention that the LB normally rests with the tube upright.

So I suppose it must just evaporated leaving any residue in it's wake to do it's corrosive thing.

Could this be a possibility guys? I had the scope out this evening and although the cell does look very poorly, the views appear to have been in no way compromised. I'm now resting the scope in the horizontal position just in case
Yep, very possible. don't cover the scope until it is dry. I always kept my Meade Starfinder upside down on it's mount. Not possible with a dob.
It's good the views through the scope are still good
