Video of installation of 4 telescopes at Willis Observatory - some nice footage of putting filters in filter wheels. Can't thank Tolga Gumusayak of TolgaAstro enough. All equipment purchased from Tolga. Nobody knows SkyX better than Tolga and very few people (he's top 10) in the world (universe) know more about astronomy equipment.
