This composite image features a captivating 2-panel mosaic of the intricate SH2-129 and OU4 nebulae, highlighting their stunning OIII-RGB emission patterns. Through the implementation of specialized filters, the mosaic vividly portrays the intricate interstellar structures and the distinct emission characteristics of these nebulae. SH2-129, also known as the Flying Bat Nebula, boasts dynamic filamentary features, while OU4, the Iris Nebula, exhibits intricate details and a captivating ring-like appearance. The utilization of the OIII-RGB technique enhances the contrast and color separation of the nebular components, providing valuable insights into the ionized gas dynamics and the underlying physical processes driving the evolution of these stellar nurseries.

Image Description and Details :

Barnard 150, also known as the Hippocampus Nebula, is a dark molecular cloud of dust in the constellation Cepheus located about 1,200 light years away.

This molecular cloud is part of our galaxy and it is one of 182 objects cataloged by astronomer Edward E. Barnard.On the right side of the image, we can see part of the squid nebula (OU4) (red signal).
