The JKT is equatorially mounted,
on a cross-axis mount, which allows operation east or west of the pier.
Normally it is east of the pier.
There are no explicit declination
Zenith distance < 84
-6 h < hour angle < +18 h (telescope
East of pier)
-18 h < hour angle < +6 h (telescope
West of pier)
The fully-lowered windshield which
sits on the dome lintel sets a further limit. Because of the asymmetry
of the telescope, the limits are different east and west of the pier.
