Improvement of the telescope system

Imaging of celestial objects is done by attaching SBIG ST9E CCD camera with UBVRI filter wheel at the prime focus of the telescope as well as using eyepiece projection method. The long exposure CCD imaging is also possible. It is usually needed to have long exposures on CCD cameras when imaging deep sky objects. During these long exposures the motion of the telescope must be synchronized with that of the object to keep the image on the same pixels on the CCD camera. In order to improve this tracking accuracy a telescope mount was designed and constructed to attach 8″ Schmidt Caasegrain telescope to the 45cm Cassegrain telescope. A CCD camera was attached to the 8″ telescope and using the CCD camera controlling software and relay switches, the direction control switches of the 45 cm telescope was manipulated so that the image on the CCD camera remains on the same position. Using this new system 45cm Telescope was guided successfully. Using this new guiding system it is possible to take long exposure images of the deep sky objects. Being able to improve the tracking accuracy of the main telescope a high signal to noise (S/N) ratio can be achieved on the spectra taken with the spectrograph
