Remarks:
During observations of a field in Perseus, we discovered fifteen new variable stars.
Our observations were carried out at the Astrotel-Caucasus observatory, located at
the Astronomical
station of the Kazan Federal university, using the 300-mm Ritchey-Chretien telescope,
equipped with an unfiltered Apogee Alta U9000 CCD camera. A total of 2316 images
with
5-minute exposures were obtained on JD 2455080–2455519. For basic reductions
for
dark current, flat fields, bias, and for removing cosmic ray
