If the weather cooperates tomorrow night I will finally get to put my new Celestron 11" Edge through its first light / maiden flight.
I have a dew heater strap for this scope that I wish to use to heat the corrector plate. This strap fits on the outside, and I'm not sure what the best position would be. I've come up with three choices:
Position 1: At the very front of the scope. The strap is directly heating the plastic and fits in front of the dovetail bar.
Position 2: Directly over the corrector. Again, the strap is directly heating the plastic, but it would have to wrap around the dovetail bar.
Position 3: Behind the corrector. Here the strap would directly heat the metal, but it could wrap through a gap between the dovetail bar and tube.
Position 4: Something else?
I've attached a picture (from the web) where I've added illustration of these three positions.
I've seen where others have placed a heater directly on the plastic ring that holds the corrector plate in place just inside the front of the tube. Is this a product that is available for purchase, or are these home-made heaters?
I'd appreciate your comments and suggestions, particularly regarding what I have now, which is a strap that wraps around the outside. But I would also appreciate alternative suggestions for a future configuration. Thank you!
P.S. More information: my dew heater is a Dew-Not for 11" CST, and the controller is a standard DewBuster. I have an aluminum Astrozap dew cover on order, unfortunately not available for me tomorrow night.
