Astrozap - Orion 150/180/190mm Mak Flexi-Heat™ Flexible Heated Dew Shield

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 or dual channel controller to be powered. Use of a dew controller other than Astrozap brand can cause damage and void the warranty.
