Further the low amount of precipitable water vapour (1–2 mm during winter) at Guru Shikhar makes it a good site for the infrared telescope observations.

[3] The Observatory is located near Guru Shikhar, the highest peak of the Aravalli Range at an altitude of 1680 metres.

Mount Abu Observatory is equipped with a 1.2m Infrared Telescope along with the following back-end instruments: NICMOS Infrared Camera and Spectrograph, Imaging Fabry-Perot Spectrometer, large format optical CCDs, Optical Imaging Polarimeter and Fibre-linked Grating Spectrograph.

[5] A new high resolution optical spectrometer, PRL Advanced Radial-velocity All-sky Search (PARAS) to detect extrasolar planets using the radial velocity technique began observation in April 2012.

This facility will have a one-meter diameter telescope with sophisticated optics and back-end instruments assembled by the Laboratory for Electro-Optics Systems (LEOS), Bengaluru.
