This letter was about the BARC image convention and the M. K. Vainu Bappu's visit.

This letter was about water vapour measurement made at Kodaikanal.

The CD contains photos of the ceremony of J. C Bhattacharya's 1.3 meter telescope. It also contains photos of various eminent persons' speeches etc.

This letter was about spectroheliograms that Saxenas sent to him. He suggested to improve on this by another factor of 200%. He explains his idea to work on spectroheliogram.

The letter is about water vapour observations. Bappu was also asking whether the point source lamp was used. He also mentioned that he would be in Bangalore on April 27.

This item was a magnetic compass which was used by M.K.Vainu Bappu during the visit to Kavalur for site survey. The magnetic compass is a tool used for determining direction on the surface of the Earth. It operates by using a magnetic pointer that aligns itself with the Earth's magnetic field. This type of compass is the oldest and most commonly used in various forms of transportation such as aircraft, ships, and land vehicles. The Earth's magnetic field acts as an enormous bar magnet with a North-South field that causes freely moving magnets to take on the same orientation. Although the direction of the Earth's magnetic field is not entirely parallel to the North-South axis of the globe, it is close enough to make an uncorrected compass a reasonably good guide. The inaccuracy, known as variation (or declination), varies in magnitude from point to point on Earth.

This item was about the interview with the director of IIA, Dr. J.C. Bhattacharya, he discussed details about the Kavalur telescope installation and its capabilities. As a co-discoverer of the rings of Uranus, Dr. Bhattacharya provided insights into the telescope's design, how far we can see from it, and other aspects of the project. He answered all questions thoroughly and provided a comprehensive overview of the telescope and its potential for sky research.

This item was about the commissioning of aisa's largest telescope. The 230cm dimetre mirror of the gaint telescope had already been polished and despite having some import issues with a vital component, the project is on schedule and there were no hitches during the commissioning process.

This item was about the Kavalur telescope was installed at the Indian Institute of Astrophysics' field station. It was housed in a specially-erected tower with a revolving dome and was known as Asia's largest telescope. Currently, the institute is in need of a more powerful telescope to carry out comprehensive research on the sky.

The item was about the design, fabrication, installation, and testing of a prime focus photometer for the 2.34-m M. K. Vainu Bappu Telescope. Photometric observations of a faint, rapid, variable star, 'AM Canum Venaticorum', were obtained during the first series of experiments. Later, Rajamohan was the project leader in discovering new objects in the solar system. Astronomers at IIA are actively engaged in the study of supernova phenomena.
