The dewshield on my 160 refractor is the stock aluminum one we supplied with all the production scopes.

Hello Roland,
 
This is a custom made dewshield I think. Made of Polyoxymethylene (POM) Delrin, Kocetal, Celcon etc...
I would like to make my own. We don't have frost here but lot of humidity, f.e. last night 98%.
 
Greetings from Bodrum, Turkey
