The Ha emission region SH2-129, commonly called the Flying Bat Nebula, contains the Squid Nebula, designated Ou4, a mysterious, squid-like apparition. This nebula is very faint Oiii emission, but als...

Explanation: A very faint but very large squid-like nebula is visible in planet Earth's sky -- but inside a still larger bat. The Giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula, are both caught in this cosmic scene toward the …

2017年9月3日 · The red (Ha Signal) is sh2-129, the flying bat nebula. The blue squid nebula (OIII signal) in this image (OU4) was discovered by the French Amateur Astrophotographer Nicolas Outters in 2011.

In the late 1950-ies the American astronomer Stewart Sharpless discovered the large nebula Sh 2-129 on the 48 inch Schmidt telescope photo plates of the «Palomar Observatory Sky Survey».

2022年8月1日 · Though apparently completely surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. More recent investigation suggests Ou4 really does …

SH2-129 is a relatively faint emission nebula in Cepheus, a neighbor of the larger and more often imaged IC 1396. Sometimes referred to as the "Flying Bat" nebula, this region is characterized by Ha emission as well as a small, mixed emission and reflection nebula (vdB 140), seen in the lower portion of the field, just to the left of center.

Recent studies suggest that OU4 lies within Sh2-129 at a distance of about 2,300 light years in the constellation Cepheus. OU4 is believed to be a bipolar outflow possibly emanating from …

Sh2-129 (R.A.: 21h 12m 20.24s, Dec: +60º 02’ 15.1”) is a Bright Nebula of Visual Magnitude 10 in the constellation Cepheus at a distance of 9318 lightyears from Earth.

Sh2-129 is an extensive emission nebula visible in the constellation Cepheus. It is located on the southern edge of the constellation, to the northwest of the large nebulous complex IC 1396, although physically at long distance from it.

The surrounding red emission nebula is part of Sh2-129, known as the Flying Bat Nebula, and at the center the Squid Nebula (OU4) . Both nebule lies at a distance of about 2,300 light years in the co...
