Astrozap flexible dew shield with built-in dew heater. This version comes with an upper and lower notch for those who have Losmandy/CGE dovetails on the top and bottom of your scope. Still attaches fine if you dont have both dovetails.
Very strong velcro ensures a snug fit and the interior is felt lined to further absorb moisture and reduce reflections. Build quality of the item is very high, this is easily the best dew shield/heater combo for a Celestron 8"/RASA on the market.
Dew Heater spec: 16 Watts @ 12 Volts (1.40 A)
Model No: AZ-820-N-2
