Remarks:
On August 16 – October 30, 2011, we obtained about 1600 images with 30-second exposures of a field in Lacerta for discovery and investigation of new variables stars. The field has the coordinates α = 22h50m , δ = +50°00′ and size 2.3°×2.3°. Here the third part of our results is presented.
Our observations were performed in the city of Krasnoyarsk with a Hamilton telescope (D = 400 mm, F = 915 mm) equipped with an unfiltered FLI ML-9000 CCD camera (3056×3056 pixels, pixel size 12 μm). For basic reductions for dark current, flat fields, bias, and for removing cosmic-ray hits, we used MaxIm DL software. The magnitudes were referred to red magnitudes of comparison stars from the USNO-A2.0 catalog (Monet et al. 1998). For search and photometry of the majority of new variable stars, we applied VaST software (developed by K. Sokolovsky and A. Lebedev, described by Kolesnikova et al. 2008). Some of the variable stars were found with C-Munipack package. To search for periods, we applied WinEfk software provided by V.P. Goranskij.
We also determined types and periods for two known variable stars (GSC 03630-00738 and GSC 03630-00750).
