Part 1 of my "How dew you dew" action for the Free State Star Party 3 - 5 June 2016
Dealing with dew at the Free State Star Party.
Maybe it will help. Some amateur astronomers are skeptical (3rd link). Maybe a disk at the back to force more air onto the mirror as suggested by the author..

- Eyepiece area
- Secondary mirror
I will give feedback after the weekend.
