  • Fine image motion controler for Kodaikanal tunnel telescope 
    Thulasidharen, K. C; Prabhu, K; Rangarajan, K. E; Vasantharaju, N; Prabhu Ramkumar, B (Indian Institute of Astrophysics, 2013-05-06)
    Automation of the spectropolarimetric observations at Kodaikanal tunnel telescope needs placement of the Sun's image on the spectrograph slit and scanning it across the region of interest. This requirement can be achieved ...
  • Full-disk synoptic observations of the chromosphere using Hα telescope at the Kodaikanal Observatory 
    Ravindra, B; Prabhu, K; Rangarajan, K. E; Bagare, S. P; Singh, J; Kemkar, P. M. M; Thulasidharen, K. C; Gabriel, F; Selvendran, R (IOP Publishing, 2016-08)
    This paper reports on the installation and observations of a new solar telescope installed on 2014 October 7 at the Kodaikanal Observatory. The telescope is a refractive type equipped with a tunable Lyot Hα filter. A CCD ...
  • An Image Auto Guider System for Kodaikanal Tower Tunnel Telescope 
    Mathur, Harsh; Thulasidharen, K. C; Hemanth, P; Nagaraju, K; Rajalingam, M (World Scientific Publishing, 2023-02)
    The Kodaikanal Tower Tunnel Telescope (KTT) is a three-mirror Coelostat-based Solar telescope. An inherent variable image drift is present in the KTT which is detrimental to observations particularly to slit-based spectroscopic ...
  • Installation of solar chromospheric telescope at the Indian Astronomical Observatory, Merak 
    Ravindra, B; Prabhu, K; Thulasidharen, K. C; Rajalingam, M; Sagayanathan, K; Kamath, P. U; Dorjey, N; Angchuk, D; Kemkar, P. M. M; Dorjai, T; Banyal, R. K (Indian Academy of Sciences, 2018-10)
    We report the observations of the solar chromosphere from a newly commissioned solar telescope at the incursion site near Pangong Tso lake in Merak (Leh/Ladakh). This new Hα telescope at the Merak site is identical to the ...
