Description:
The results of the spectral classification of 1224 O-M stars of
different luminosity classes in the region of NGC 2175 and around it
are presented. The classification has been carried out on the basis of
low dispersion objective prism spectra. Using the B-V and U-B data for
106 stars out of 1224 the MK classification has been done with the
photometric Q-method.
