The public Star Party at the Diefenbunker in Carp has been given a green light for tonight. I will be there with my Celestron 8" Evo, and will be demonstrating the DIY/Homebrew Gen3 (HBG3) devices

Thanks for sharing that. Great presentation btw. Blowing air across top of mirror from back to front makes a lot of sense. I've seen designs where they place a fan in each corner of the mirror box
