Abstract: An inexpensive and automatic computerised telescope orientation system (ACTOS) developed in-house has been described, which controls the orientation and tracking of all the old Pachmarhi array of Cerenkov telescopes consisting of 46 parabolic mirrors, mounted on 22 independent equatorial mounts. This PC-based system has a mean pointing accuracy of 0o.1 in both E-W and N-S direction. Earlier the array was controlled by a system of gears, driven by stepper motors one each in East-West (E-W) and North -South (N-S) direction. ACTOS was designed specially for the experiment being conducted at Pachmarhi (India) to search for very high energy (VHE) gamma rays from celestial sources.
