We present our approach to search for new variable stars in archival data of the D50 telescope. The pipeline uses a maximum variance method combined with a minimum path criteria to eliminate false positives. Both single night and multi-night approaches are tested. The method clearly identified twelve variable stars in the two testing fields. While newly identified variable stars are still in the process of classification, as an example we present the observation of a Mira Ceti type star V1286 Cyg, which the system discovered without prior knowledge.
