  • A New Digital Display System for the 1-meter Telescope at Vainu Bappu Observatory 
    Srinivasan, R; Naidu, B. N (Astronomical Society of the Pacific, 1997-01)
    The Carl-Zeiss 1-meter telescope at Vainu Bappu Observatory uses synchro transmitters as angular transducers in a 3-stage geared train for the two axes coordinate display system. Synchro receivers are used in the console ...
  • Object-oriented programming approach to CCD data acquisition and image processing 
    Naidu, B. N; Srinivasan, R; Muralishankar, S (SPIE-The International Society for Optical Engineering, 1997-10)
    In the recent past both the CCD camera controller hardware and software have witnessed a dynamic change to keep pace with the astronomer's imaging requirements. Conventional data acquisition software is based on menu driven ...
  • Performance of the IIA mosaic CCD camera system 
    Naidu, B. N; Srinivasan, R; Mohan, V; Sagar, R (Astronomical Society of India, 2001)
    We evaluate performance of the 4K x 4K mosaic CCD camera system developed at the Indian Institute of Astrophysics using four Thomson CCDs in a buttable configuration. The camera system consists of a mosaic CCD dewar developed ...
  • Personal computer based star changing device and occultation data acquisition system 
    Srinivasan, R; Naidu, B. N; Vasundhara, R (Council of Scientific & Industrial Research, 1993-01)
    This paper describes a personal computer interface card developed for occultation studies with the 1 m telescope at VBO Kavalur. The new feature of this system is the application of a personal computer for the accurate ...
  • Search for Hydrogen-alpha Emitting Cool Pockets in Corona During the Total Solar Eclipse of October 24, 1995 
    Cowsik, R; Singh, J; Raju, K. P; Saxena, A. K; Samson, J. P. A; Naidu, B. N (Indian Institute of Astrophysics, Bangalore, 1997)
    Narrow pass band hydrogen alpha filtergrams were obtained during totality at Kalpi, to look for cool pockets of H-alpha emission in corona first observed by Bappu and Bhattacharyya during the 1970 Mexican eclipse observations. ...
