## Description

Dew prevention shield for Celestron 8" SCT/EdgeHD/RASA telescopes

Review: Performed as advertised! - I’m very pleased with the fit. Perfect alignment and easy engagement. It seems very secure on my NexStar 6se OTA. Had it out this morning and had no light leak issues. It’s worth the money spent. I’ll get one for my next larger scope.
Review: Best dew shield I have owned for my various SCTs.... this one is the 8" size. - I have various SCTs including 8", 11", and a 14". This by far is the most well designed dew shield I have owned for those scopes. It is stiff enough so will hold up to some abuse, I like the side port to run cables out as use it in Hyperstar mode so need to get the camera USB, power, and also the internal Celestron dew heater ring cables out of the shield. It fits well and the clamping mechanism is good. One big plus is that they include a nice aluminum cover. Since the stock cover won't fit on the dew shield I always had to make my own caps for my other scopes which is a pain. I could remove the dew shield on the other scopes and use the stock cover but that is an issue with Hyperstar as I do NOT want to remove the camera, Hyperstar, etc. every time I want to cover the scope after using it. I haven't found any negatives although I did decide to put some Rrvnuts with plastic thumb screws on the dew shield so I could ensure a tight and secure fit so it wouldn't get knocked off as I covered the scope for the night. The stock clamping setup is pretty good but I wanted the extra peace of mind ;-)
