sh2-150 - vdb154
emission and reflection nebulae
Sh2 -150 is an emission nebula and Vdb154 is a reflection nebula.
They are visible in Cepheus, identified in the central part of the constellation, at about one fifth of the angular distance between ι Cephei and μ Cephei; the most suitable period for its observation in the evening sky falls between the months of July and December and it is considerably facilitated for observers located in the regions of the terrestrial boreal hemisphere , where it is circumpolar up to the warm temperate regions. Sh2-150 is a fairly large H II region oriented north-south slightly east of 26 Cephei ; it lies at a distance of about 900 parsecs (over 2900 light-years ) Visually near to Sh2-150 is the reflection nebula VdB 154. Its distance is not yet known, therefore is not possible to claim that there is a physical link between both nebulae. Some dark clouds also can be seen on the image
