AstroZap Flexi-Heat Telescope Dew Shield for 16" SCT Telescopes    Turn up the Heat with the Flexi-Heat Dew Shield by AstroZap!    The AZ-815 Heated Dew Shield has been expertly crafted for a Meade or Celestron 16” SCT or optical tubes with a 444mm outer diameter.    Until now, standard unheated dew shields could only prolong the onset of dew formation.

Why not add some heat?   Our Flexi-Heat dew shields direct the heat right to your optical tube assembly, thus eliminating any chance of dew formation. Guaranteed!   What makes it work?   The source of heat is a thick film heater manufactured for operation at 12 volts.
