Telescope NameTelescopeFeaturesSample image
B240.61m Corrected Dahl-Kirkham TelesocpeThis open truss telescope is used mainly for faint object research.
B14 0.35m Schmidt Cassegrain TelescopeThis close tube telescope is used for general purposes. it has been routinely used for asteroid photometry, astrometry, comet imaging, comet photometry. Also Nova and supernova astrometry and astrophotography.
B14HD0.35m Schmidt Cassegrain HD TelescopeClosed tube telescope is used for satelite observation. Asteroid photometry, astronometry, comet imaging.
B120.30m Schmidt Cassegrain Telescope This close tube telescope is used mainly for astrometry. It is also suitable for asteroid photometry, comet imaging, comet photometry, nova and supernova astrometry. The Johnsons and Cousin photometric filters are suitable for accurate photometric work. We also use this telescope using Narrow band imaging.
