- defrost heater
Astrozap Flexi-Heat Dew Shield for 11 "Celestron SCT / CGE and HD w / Two Notch is great.
This product is very good. Flocked paper is pasted on the inside. Therefore, stray light can be prevented. In addition, since it has a built-in defrost heater, it can prevent the lens from becoming cloudy when it is humid. I'm glad I bought this product. Then OPT sent me this product right away. A great dealer.
Works but give it time
Went out to see the planets at 4 am this morning - ambient temp 38 F / Dew point 36 F. Dew quickly formed when I took off the cover I had placed over my 11" SCT. Had never used the Astrozap before but easily attached and applied maximum power. Took about an hour for the dew to dissipate but it did. Lessons learned - put the dew cover on ASAP! After an hour outside, I started to have a problem with condensation on my eyepieces too so know I need to get dew strips for those too. Every session with the scope is a learning experience. It's awesome!
Works great all night, even in heavy dew!
works so much better than a regular dew shield
Flexi-Heat Dew Shield Absolutely Performs
Easy to apply, fits perfectly, clings tightly to my OTA. I don't have to worry about it shifting during fast slews, and it does a wonderful job of keeping my optics completely free of condensation in these humid midwestern nights. When my shoes get wet from the dew soaked grass, I know my optics will remain bone dry. Well worth the price!
