Sh2-170 is an emission nebula in the constellation Cassiopeia. Its main emissions are in Ha wavelength with a dim OIII area in the center part. The nebula is associated with a small star cluster in its center.

The Ha data were captured in 2019 with a TS 130/910 Photoline apo and an ASI1600mmp. The OIII and RGB data are from 2020 with the same setup and a TSRED379 reducer in the optical train.
