Just a heads up for those who might have their gear living in a Dome or roll-off observatory.
While doing a clean up in my observatory, I noticed some white spots on the drawtube of my AP155.
They didn't wipe off!
...they turned out to be small corrosion spots from Arachnid droppings no less!
AP are now re-working and re-plating the drawtube (cost TBA...but I suspect it won't be cheap)
More insect surface spray and a cover sheet is now in place !
