Any quality optical lens tissue and cleaning fluid specifically designed for multi-coated optics can be used to clean the telescope’s objective lens as well as the lenses of the eye- pieces and finder scope. Never use regular glass cleaner or cleaning fluid designed for eyeglasses. Before cleaning with fluid and tissue, blow any loose particles off the lens with a blower bulb or compressed air, or lightly brush the lens with a soft camel hair brush. Apply some cleaning fluid to a tissue, never directly on the optics. Wipe the lens gently in a circular motion, then remove any excess fluid with a fresh lens tissue. Oily fingerprints and smudges may be removed using this method. Use caution; rubbing too hard may scratch the lens! On larger lenses, clean only a small area at a time, using a fresh lens tissue on each area. Never reuse tissues.
The ShortTube 80-A includes a soft-sided carrying case. The carrying case will hold the ShortTube 80-A safely dur- ing transport and doubles as a convenient storage spot when the telescope is not in use. You will need to remove accessories such as the eyepiece, star diagonal, and finder scope in order to place the telescope into the case. The finder scope can be stored on top of the padded velcro flap that covers the telescope. The other accessories can be stored in the exterior pockets of the carrying case for easy transport.
