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..

 Will use the fan  in combination  with heater made from nichrome wire (old electric blanket).
- Eyepiece area
- Secondary mirror

I will give feedback after the weekend.
