Sh2-170, sometimes called the "little rosette nebula", is a faint, nearly circular hydrogen-alpha region in Cassiopeia. ?It surrounds a small young cluster of stars that provide sufficient ionizing radiation to make the nebula glow. Stellar winds from the new stars and embedded dust in the hydrogen gas combine to create the complex visual structures.

The image was captured during 4 nights in September 2024 from SkyPi Remote Observatory using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final HaLRGB integration of 16.5 hours.?
