Lesedi can safely point between 30° and 89° above the horizon, at any azimuth. There are no obstructions in the dome to be aware of (assuming the observing floor has been checked for ladders etc).
If the telescope reaches an altitude limit, it will simply stop tracking and can be pointed to a new position. Note that the TCS will not warn you that the limit has been reached. The azimuth rotation is limited to a range of 400° in order to avoid twisting the cables that pass through the pier. It is therefore possible to encounter an azimuth limit while tracking, but this should be rare because the limits are in the West. If a limit is reached, the telescope should automatically "unwind" by 360° in azimuth and continue tracking (if it doesn't, simply repoint the telescope), but in an effort to avoid this scenario, . If the telescope is programmed with within 40° of an azimuth limit when slewed to a target, it will "unwind" on pointing if an attempt is made to point within 40° of a avoid the limit.
