NGC 6910 is the northern hemisphere open cluster known to be rich in β Cephei-type stars. Using four-season photometry obtained in Białków (Poland) and Xinglong (China) observatories, we performed variability survey of NGC 6910. As the result, we found over 100 variable stars in the field of the cluster, including many stars showing variability due to pulsations and binarity. Thanks to the spectroscopic observations, we also detected changes in the profiles of spectral lines of β Cep stars, caused by pulsations.
