Description
The 1.3-m Devasthal Fast Optical Telescope (DFOT) from DFM Engineering Inc. USA is installed at the Devasthal site of ARIES. Telescope has a fork equatorial mount, friction drives for its motions and is enclosed in an in-house fabricated roll-off roof. It is used for various scientific observations such as follow-up of transient events, studies of variable stars, star clusters and galaxies etc. The auto guider of the telescope has a pick-off mirror, guide camera and a filter slide. The filter slide has a provision for mounting eight filters. The linear motion to the filter slide is through the motorized arrangement. Presently, observations demanding fast sampling of images are limited due to the slow motion mechanism. Trials of fast motion with the existing system were performed in the past but had limited success due to various limitations in the system. Upgradations in the motion mechanism of the filter slide are planned with a modified system. The presentation will discuss the limitations in the present system and modifications in progress for the existing system to minimize the time delay between two successive science observations.
