Aims. We verify the nature of emission-line stars in the field of the open cluster NGC 6910. Methods. Spectroscopy in the H α region was obtained. Raw CCD frames of spectra of all stars fainter than V = 9 mag observed by us are significantly affected by nebular emission originating in the surrounding $\ion{H}{ii}$ region IC 1318. After careful data reduction and subtraction of the nebular radiation we succeeded in obtaining reliable stellar spectra. Results. We confirm that the star NGC 6910 37… Expand
