Sh2-129 is a Bright Nebula of Visual Magnitude 10 in the constellation Cepheus at a distance of 9318 lightyears from Earth. It is one of the many beautiful H-alpha emitting objects that can be found in the Sharpless catalogue. The nebula is also known as Flying Bat Nebula.

The Squid nebula (ou4) occupies over one degree of the night sky, representing the largest angular extent ever found in a planetary nebula. Known colloquially as the giant squid nebula, it is physically nearly 50 light years across. This bipolar nebula could be one of the nearest of its type known, situated around 2300 light years away, though it being a planetary nebula needs confirmation.
