The Merry-go-round observatory put me in mind of “A PRACTICAL HEATED OBSERVATORY BY E. G. HILL” in the 1962 JBAA V72,3 p102. A similar idea based on a newtonian reflector. No video though. It might have appeared on the Sky at Night as the report predates my membership but I have strong memory of it.
