The first observations with the 25 cm telescope of the Shumen AstronomicalObservatory led to the following conclusions: (a) Intra-night observations ofvariable stars with an amplitude larger than 0.1 mag are possible down to 14mag with an acceptable quality with this setup; (b) The equipment is suitablefor observations of bright extended objects with sizes up to 30 arcmin(planets, comets, clusters, nebulae, galaxies) with resolution 0.88 arcsec/pix;(c) The guiding of telescope is very good which makes the equipment appropriatefor prolonged patrols; (d) The observations with the 25 cm are already fullyremote-controlled; (e) The determined transformation coefficients allowtransfer from instrumental to standard photometric system BVRcIc andrealization of differential photometry.
