For Astro-Tech Telescopes

Each Astrozap dew shield/lens shade below is made of lightweight, flexible, and durable black ABS plastic. It is lined with black felt to absorb moisture and light. Aside from retarding the formation of dew during nighttime observing, it acts as a lens shade to block neighboring lights and provide a sharper and higher contrast image when doing astronomical imaging from a light-polluted city or suburban site.

Simply wrap the Astrozap dew shield around your R-C’s front cell. The ends of the dew shield overlap and Velcro strips on the overlapping ends hold it firmly closed in a tubular shape. The Velcro strips are sewn in place for durability. A two-inch wide strip of foam rubber inside the end of the dew shield clasps the telescope optical tube front cell snugly to prevent any slippage of the dew shield during use.

Storage is easy. You can roll the Astrozap up like a newspaper and fasten it with a rubber band or string to stand out of the way in the back of a closet when not in use. Alternatively, you can store it open and flat in the top of your telescope carrying case or standing on end out of the way in the back of a closet.
