The Astrozap Flexible Heated Dew Shield uniquely combines both active and passive methods of dew fighting with the added feature of shielding the telescope from undesirable stray light. Felt-lined to help absorb moisture and to prevent extraneous light from reaching the optics and greatly improve contrast. Astrozap heated dew shields are made from the highest quality ABS-grade polymers. VELCRO® Brand fasteners provide a snug fit and padded so as not to mar or scratch the telescope's finish. They roll up easily into a convenient size for easy transportation to star parties and dark sky sites. This product requires the use of a simple D/C adapter (AZ-719) or dual channel Astrozap Dew Controller (AZ-720) to be powered. Use of a dew controller other than Astrozap brand can cause damage and void the warranty. Proudly manufactured in the USA!
