Abstract

Interstellar extinction is investigated in a 1.5 square degree area in the direction of the reflection nebula NGC7023 at l=104.1{deg}, b=+14.2{deg}. The study is based on photometric classification and the determination of interstellar extinctions and distances of 480 stars down to V=16.5mag from photometry in the Vilnius seven-color system published in Paper I (2008BaltA..17..161Z). The investigated area is divided into five smaller subareas with slightly different dependence of the extinction on distance. The distribution of reddened stars is in accordance with the presence of two dust clouds at 282pc and 715pc, however in some directions the dust distribution can be continuous or more clouds can be present.
