The telescope is housed with a seven-story, circular, concrete building. It was designed to withstand the high winds prevailing at that location. The slit is narrow. The dome is required to move with the telescope to avoid obstruction.
Of course we decided to venture up the mountain to take a peek and some photos. A short distance from our destination we heard a noise in the 4wheel drive's back wheel, upon investigation it was discovered that an Allen key was lodged in the tyre. Everything was taken out of the back and tyre changed but being a Sunday no place was open in Coonabarabran to have the tyre repaired, so we drove some distance to the next town for repairs the next morning.
