Storage and Cleaning We recommend storing all equipment in an air tight container with desiccate packages to remove unwanted humidity from the air. Never leave the telescope in a humid environment, and avoid leaving the scope in a hot heated environment. If not properly stored, it is possible for the scope to develop mildew growth or other preventable conditions. Be careful after a night of observing when conditions might leave dew on the lens, and allow the scope to air dry in a room temperature environment before storing the telescope. If the front lens surface becomes dusty, smeared, shows fingerprints, or any other surface build up, the following steps can be taken to clean the lens. First, gently blow away any surface dust or particles with a clean air blower (canned or compressed air is not recommended). Second, use a photographic quality optical cleaning solution and cloths to gently wipe the surface clean. The Zenithstar has a beautiful high gloss anodized finish that can be easily smudged with fingerprints; however this will not harm the finish. A slightly dampened clean soft cloth with plain water should be enough to clean the surface.
