Intensified CCD Camera Based Remote Guiding Unit for VBT and Observation of Speckles with ICCD

Chinnappan, V; Saha, S. K; Faseehana (Indian Institute of Astrophysics, Bangalore, 1991)

For successful observations in any telescope, guiding becomes important. On 2.34 m Telescope at Vainu Bappu Observatory, Kavalur, a remote guiding system is assembled using Intensified CCD camera and a PC based image ...
The Microprocessor control of the Kavalur 234-cm optical telescope

Chinnappan, V; Bhattacharyya, J. C (Astronomical Society of India, 1985-06)

This paper gives an introduction to the control system of the 234-cm optical telescope. The computer used in control is based on an INTEL 16 bit microprocessor. The VAX 11/780 system has a supervisory role in the control ...
Narrow Band Photometry in Emission Lines during the Total Solar Eclipse of October 24, 1995

Singh, J; Cowsik, R; Venkatakrishnan, P; Srinivasan, R; Chinnappan, V; Raju, K. P; Srikanth, R (Indian Institute of Astrophysics, Bangalore, 1997)

To investigate the spatial variation of tempereture and density within coronal strucures, narrow band photometry in three coronal emission lines was done during this eclipse. The emission lines 6374 (FeX), 7892 (Fe XI) and ...
Telescope drive requirements and design of a Microcontroller based drive and display system

Chinnappan, V (Indian Institute of Astrophysics, Bangalore, 1993)

Optical telescope is a precision instrument which gives images of stars and galaxies when the telescope is pointed towards them. To design a good telescope drive, the requirements of a good telescope is to be well defined. ...
