Data Acquisition from 2020-10-21 until 2020-12-18

DSO Color Mapping: Stars RGB, Nebulae Modified Hubble Palette

Original Image Scale: 4.00

---------------------------------------------------------------------------------------------------------------------------

This is a seldom imaged area in Cepheus. Much of the "bright" nebulosity in this image is dim enough to be considered just interstellar material without any catalog designation. That being said, this roughly 6 degree image features several cataloged objects, primarily the complex of dark nebulae Barnard 169 to 174, and the bright HII regions Sh2-134 and Sh2-135.
