Recommended dew/frost heater system for C14 Edge HD ?

 

I am seeking recommendations for a dew/frost heating system for my C14 Edge HD.

Last year during my Jupiter observation campaign I used a hair drier but it was kind of noisy in the middle of the night.

Thanks in advance for any replies.

OPT has several options.? A heated dew shield is the most aggressive.?Using a heater without a shield may not work due to the large size/area of C14

I made a cheap dew shield using a thin, dense camping pad and some duct tape.? It works very well for at least 4 hours, after which a hair dryer can re-start the process.

I use heating tape with dew-not controller (usually set to maximum) in conjunction with Dew-Shield. Works on most, but the dewiest nights. In those rare cases I use hair drier on low setting. Very gently.

I use a heating tape and a dew shield on my C14HD.? However,?I've mounted the heater strip on the inside housing of the corrector.? There is just enough room to keep it out of the optical?view.? I'm?using the shorty aluminum dew shield, as it is the only one with cut-outs for the mounting plate and an accessory rail on top.? The double layer of aluminum seemed too thick for an externally mounted dew strip to be effective, so I moved it inside and the wire is directed through the hole intended for a Fastar cable.? Maybe not an orthodox system, but it works here in central Maryland.? Lou

I have my dew heater under the corrector plate as well. The lip of the retaining ring is plenty big to hide it from the light path.?
When I had the scope apart to add the rear cooling fans and flocking it seemed like a perfect idea.
The thin wires run under the internal flocking down to a jack on the rear of the scope to the power controller.
?Using a short ?aluminum dew shield it is good all night (if set right).
Probably more than you want to get into, but it really works.
CERTAINLY not recomended for a scope in warranty!
Just FYI
