Tennant; he is a strict, honest person and has the skills of an observer.

This item was about the measurements of spectrum and solar spots. It is divided into two parts. The first part describes the scale division of the spectroscope micrometer that defines the bright lines observed in the spectrum of the southeast by east prominence and the ordinary lines in the solar spectrum that were measured before and after the eclipse. The second part includes a sketch depicting the principal solar spots measured at Masulipatnam on August 18, 1868. The sketch shows four spots: A, B, C, and D.

The fond contains Results of observations of the fixed stars made with the Meridian Circle at the Government Observatory , Madras

The fond contains Result of astronomical observations made at the honourable, the East India company's Observatory at Madras volume 1 to 5.

This item was a optical instrument named as Stereoscope. Stereoscopes are apparently those optical devices that help to view the two images separately and with relaxed eyes. There are two types of stereoscopes as: lens or pocket stereoscopes and mirror stereoscopes. Lens or pocket stereoscopes are great for viewing the whole overlap area of prints up to 9 cm × 13 cm or parts of larger patterns. On the other hand, mirror stereoscopes were designed to accept standard 23 cm × 23 cm metric air photos and work well with A4/US letter-sized prints. Most models come with magnifying options up to eight times, which is pretty impressive. One cool thing about mirror stereoscopes is that they are large enough to allow the analyst to draw beneath them, so it is possible to trace objects identified in the stereoview with a pen onto one of the images or a transparent overlay. However, it's important to remember that this sketch wouldn't have the geometric properties of a map as it contains all distortions present in the base image.

This item was about the total solar eclipse that occurred on 16 February 1980. In this photograph, we can see that only the Sun's corona is visible to us and captured.

The item comprises observations notes of the separate results of Madras Meridian Circle Observation by N. R.Pogson in 1864 and 1875.
