Why not drape netting with draw strings, much like a window blind configurationthat opens with the roof and a hole for the OTA to poke through that has an elastics material surrounding the hole. With enough slack it should slew with the scope quite easily. Have I done this ? God no! Will I try it when mu Obs. is finished, absolutely!
