Meade II 90mm User Manual - Page 13

Cleaning Should your filter get a build up of loose dirt particles on any surface use a static free lens brush to gently "sweep" it clean. Fingerprints and other residue can be cleaned using a high grade optical solution applied to an optical tissue. Using a circular motion work from the outside edge in towards the center. As these are hard coatings you can be firm but do not rub. Finish with an anti-static lens cloth. All of these cleaning items can be purchased through a camera/telescope dealer. Never use the following items on any section of your filter. 1. Compressed Air 2. Acetone 3. Anything with acidic properties 4. Any fabric not intended to clean optical coatings 5. Household cleaners If you have questions please contact our customer support. Care The telescopes and filters, if used properly, will not degrade with exposure to the Sun's rays. You may leave your system set up in the Sun, even tracking the Sun, all day without risk. When your system is not being used it should be stored in a cool, dry location in the foam-lined case it was shipped in and with the included protective caps securely in place. In locations with excessive humidity placing a silica packet in the box is advised. Provided you do not drop or subject the telescope or filter to rough handling, it will work as well years from now as it does today. We use hard coatings throughout the system to ensure uniform performance for years to come. It is safe to carry your filters on airplanes and to pass them through X-Ray machines.
