Celestron SS80 - Storing Your C90.19; Technical Specifications.19

Due to the weight of some video cameras, you may need additional
support.
Storing Your C90
To minimize the need to clean your C90, replace all lens covers after
use. The spotting scope can be left on a tripod for display purposes or
returned to its carrying case. Since the rear cell of your C90 spotting
scope is not sealed, the eyepiece or plastic cover MUST be placed over
the opening in the rear cell when not in use. This will prevent con¬
taminants from entering the optical system.
