Durable, flexible ABS plastic that won’t chip or break like hard dew caps. It wraps snugly around the telescope tube and fastens with Velcro. FlexiShield can be stored flat or rolled up for convenient storage and transport.
Bought for my NexStar 11 GPS, but doesn't fit tightly due to fork OTA attachment bars. Never used. $40 new from Orion. Includes shipping. Money order or (preferably) PayPal.
