dew problem

[orionoffelt]

I am busy at the moment setting up my Celestron 11" CPC scope in my new observatory and last night trying to get my polar alignment right noticed that even with my scope tube dew heater on from half to full power it still only cleared the outside of the corrector lens and left dew in the centre of the corrector I have got a flexable dew shield but with me only setting things up did not bother to fit it. Do you think this would solve the dew problem and give me more imaging time when I get the system up and running or would I have to use my 12 volt hairdryer ?

cheers

A dew shield will help, as would a second dew strip if it gets really bad

(Kelling star party, Sept 2008, I had two dew strips and a dew shield on my C11, and it still dewed up in 15 minutes!)

Thanks steveL for the feedback I will see how the dew sheld helps
