Yes, there are several telescopes located in the Himalayan mountains. The high altitude and clear skies of the region make it an ideal location for astronomical observations. In this answer, we will discuss some of the telescopes located in the Himalayas.

Hanle Observatory: The Hanle Observatory is located in the Hanle region of Ladakh in the Indian state of Jammu and Kashmir. It is one of the highest observatories in the world, situated at an altitude of 4,500 meters above sea level. The observatory is home to several telescopes, including the Himalayan Chandra Telescope (HCT), which is a 2.01-meter optical-infrared telescope that is operated by the Indian Institute of Astrophysics. The HCT is used to study a range of astronomical objects, from stars and galaxies to exoplanets.

Indian Astronomical Observatory: The Indian Astronomical Observatory (IAO) is located in the village of Hanle, Ladakh, at an altitude of 4,500 meters above sea level. The observatory is operated by the Indian Institute of Astrophysics and is home to several telescopes, including the 2.3-meter Vainu Bappu Telescope, which is used to study galaxies and quasars.

Devasthal Observatory: The Devasthal Observatory is located in the Devasthal region of Uttarakhand in northern India. It is situated at an altitude of 2,500 meters above sea level and is operated by the Aryabhatta Research Institute of Observational Sciences (ARIES). The observatory houses several telescopes, including the 3.6-meter Devasthal Optical Telescope, which is one of the largest telescopes in Asia. The telescope is used to study a range of astronomical objects, including stars, galaxies, and black holes.

Mt. Abu Observatory: The Mt. Abu Observatory is located in the Aravalli mountain range in Rajasthan, India. It is situated at an altitude of 1,722 meters above sea level and is operated by the Physical Research Laboratory (PRL) of India. The observatory houses several telescopes, including the 1.2-meter infrared telescope, which is used to study the infrared radiation emitted by astronomical objects.

In conclusion, the Himalayan mountains are home to several observatories and telescopes that are used for astronomical research. These observatories take advantage of the clear skies and high altitude of the region to observe the universe in greater detail. The telescopes located in the Himalayas have contributed significantly to our understanding of the cosmos and continue to play an important role in astronomical research.
