what scope Alex?
most times both

[Matty P]

Probably a dew heater would be the best. However I suggest you use both for better results.

My 6" achro has a shield, and is heavily affected by dewy conditions...

My new 80mm scopes have shields, and I bought heaters to counter the problem..

I would (and did) go with both.

Depending on the scope probably both...

What kind of scope is it?

[alex79]

the C11 adn there will be a WO Z66 on top of it

[Rigel003]

The C11 needs a dew shield and a heated dew strip too. It will dew up in the blink of an eye.

[alex79]

i know tell me about how quick it does

[alex79]

now for the second part of my question what heat straps to use orion or kendrick ? and any experance with the differnaces between them both as they look the same to me

[madtuna]

ah Alex I should have known :P

Yep the C11 you'll definately need both as the corrector plate is right on the front and open to the dew.

Have a browse through the ATM forums and you'll find some good tutorials on how to build both.
The 66 has a small dew shield so you may just need a heater strap.

I've just bought the Orion Dew Zapper and a couple of straps for my 2 80mm's haven't had them out yet for a test, but it looks a hell of a lot like the Thousand Oaks system, which works very well... If you're handy with electronics, making a PWM controlled dew heater system is pretty easy... I just dont like the finish of any of my home built projects so I went with a commercial one :) (lazyness wins 90% of the time)

[alex79]

Like yourself, no.. 100% lazy so comerically built works best my way

After having recently acquired Thousand Oaks system through SDM, I can say I'm very satisfied (no commercial interest or kickback) I just like things that work when they arrive in the mail, have a good finish and are functional.
