Here’s my latest shot of the Flying Bat & Squid Nebula (SH2-129). I tried this target a couple years ago but this time I devoted 24 hours solely to the Oiii channel so the squid can easily be seen.

A deep-sky image showing the sprawling, faintly glowing structure of the Giant Squid Nebula (Ou4) with long, thin, blue-tinted lobes resembling a squid's arms stretching diagonally across the frame. The nebula is immersed in a wider field of reddish hydrogen emission from Sh2-129. Near the center is the bright triple star system HR8119, thought to power the outflow. Countless background stars are scattered across the dark sky.

A stunning telescopic image reveals the Giant Squid Nebula (Ou4) nestled within the larger Flying Bat Nebula (Sh2-129) in the constellation Cepheus. The vibrant blue-green Squid Nebula, a bipolar outflow from a triple star system (HR8119), contrasts beautifully against the reddish hydrogen emission of the Bat Nebula. This composite image, created from 55 hours of narrowband data, spans 3 degrees of the sky, showcasing the incredible detail of these cosmic structures approximately 2,300 light-years away.

Stunning telescopic image showcasing the Squid Nebula (Ou4) nestled within the Flying Bat Nebula (Sh2-129) in the Cepheus constellation. The image, a composite of 20 hours of data, reveals the Squid Nebula's distinct bipolar shape and its possible location within Sh2-129, approximately 2,300 light-years away and spanning nearly 50 light-years. The reddish hues represent hydrogen emission from Sh2-129, while the blue-green highlights doubly ionized oxygen in Ou4, potentially an outflow driven by the triple star system HR8119.
