Abstract:
We present the results of CCD photometry in the seven-color Vilnius
system for 922 stars down to V∼17mag in a 1.5 square degree field at
the northern edge of the HII region Sh2-205, at the Perseus and
Camelopardalis border. Using the intrinsic color indices and
photometric reddening-free Q-parameters, two-dimensional spectral
types for most stars are determined.
Description:
Seven-color CCD photometry in the area shown in Figure 1 was obtained
in October of 2010 with the Maksutov-type 35/51 cm telescope of the
Moletai Observa- tory in Lithuania, equipped with a VersArray 1300B
liquid nitrogen cooled camera. It has a backside-illuminated
1340x1300 pixel chip with pixel sizes 20x20um and with Unichrom
UV-enhancement coating. More information about the camera, including
its sensitivity function, is given by Zdanavicius & Zdanavicius
(2003BaltA..12..642Z 2003BaltA..12..642Z). The image scale is 3.38" per pixel, which
results in a field size of 1.26°x1.22°.

Note (1): ** indicates that stars were not classified in two dimensions since
their images are asymmetrical, i.e., these stars are double or multiple.
The components of some of them are seen separately but they are closer than 7".
