The intention from the start was to make the observatory (Dome and Telescope) remotely operable with the potential for automated observations. The offer of the old Pex Hill dome seemed like the answer. The main problems being wind shake (due to the telescope being in the open air), set up time and awkwardness of moving the run off shed (which by now was getting difficult to move). This work reasonably for a few years, but not much in the way of observations had been done. The 18 inch telescope ended up being used on an AltAz fork mounting within the old TRO 30inch run off shed at the bottom of the garden at Church Lane. Telescope and observatory design and construction The 18inch F5 used at my old house for many years was moved to Church Lane back in From 1997 to 2000 the telescope did not do any observations due to the building of the 30 inch TROK telescope and two 16 inch F6 Dobsonian (to name a few).
