dc.description.abstract 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 by controlling the tilt of the secondary mirror. Hence a fine image motion controller for secondary mirror in Kodaikanal Tunnel Telescope was developed and tested with telescope. A slo-syn stepper motor drive model SS2000D6 was used for driving the Steper Motor HS50. A multi function PCI board from measurement computing model PCI 2517 was used in giving signals to the drive. Control software and user Interface were developed. The system was calibrated to facilitate regular observations. en
