We developed software for detection of variable stars using CCD photometry.It works with "varfind data" that could be exported after processing CCD framesusing C-Munipack. Our goals were maximum automation and support of large fieldsof view with thousands of stars. The program chooses the comparison starsautomatically, processes all time series using multiple comparison stars to getfinal light curves. Different filtering algorithms are used to reduce theimpact of outlying points, imaging artifacts and low quality CCD frames withoutcareful manual time series reduction. We implemented various variable detectionindices and plotting two-channel diagrams of selected pair of indices and meanbrightness of the star to distinguish variables from constant stars for furthermanual check of outlying points as variable candidates.
