Ken Owen's flip top observatory was the inspiration for the hinged shelter I built for my 20 inch ball scope, pictured above. Instead of elevating the observing platform, which made it possible for him to use counterweights to balance the canopy, I preferred a ground based platform. To help in lifting the canopy I eventually added two gas springs which compensate the weight to help lift it to its retracted, vertical position.

This type of hinged shelter is ideal for large, dobsonian telescope use and storage. It is much more convenient for dobs than roll-off-roof or rolled shelters and much cheaper to build. There are no walls to block the view, the scope can leave its pod to be moved elsewhere if trees or buildings are blocking the view. With the very convenient integrated, retractable desk there is room to place the eyepiece box, atlases, computers, etc.
Ken Owen showed us an unusual shelter for his older generation GEM mounted Newtonian that turns out to be particularly well suited to today's modern, dobsonian type telescopes.
