I have a CPC800 and have been using it for about a year. I noticed some moisture condensating inside the corretor plate. In the page 44 of the manual, they say "...remove the accessories from the rear cell of the telescope. Place the telescope in a dust-free environment and point it down". As far as I know, this is the first time in the manual that these words show up: "rear cell". I want to make sure that I am understanding what they are saying: is it to remove the visual back, star diagonal, whatever is attached? Is that right?
