Around Sh2-207,210
This image has captured dimmed Hα regions positioned on a boundary line of Perseus and Camelopardalis. The boundary line is crossing center of this image in east west direction. A left one with a size of about 20 arc minutes is Sh2-210 in Perseus, and two paralleling nebulae in right hand side belong to Camelopardalis. Sh2-208 is most striking in them, Sh2-207 just south of it is very dimmed with a span of about 13 arc minutes.
