1.2-m @ PRL
The 1.2-m telescope was designed and built indigenously by the SHAR Center of ISRO.
The telescope is on a fork mounted equatorially. All the original electronics has been
replaced by PRL's engineers in recent times and the current version of the electronics
and control/drive system is controlled by a Linux PC. The software is also developed
in house. Apart from normal 'sidereal' tracking, it is also possible to have non sidereal
rate tracking for observing fast moving objects like comets and asteroids.
The telescope is operational since December 1994.
