Every owner of a Schmidt-Cassegrain or Maksutov-Cassegrain telescope knows what a pain dew can be. When it forms on the front corrector plate or lens, it's usually time to call it a night.

This 90mm (3.5") OTA FlexiShield dew cap is the answer. It reduces the formation of dew, prolonging your observing sessions.

It's made of durable, flexible ABS plastic that won't chip or break like hard dew caps. It wraps snugly around your telescope tube and fastens with Velcro. FlexiShield can be stored flat or rolled up for convenient storage and transport.

It also makes an excellent lens shade when using your telescope in daylight.
