Sh2-129 “Flying Bat Nebula”

This image is the sum of 7 Ha frames of 1800s. It ha been taken on September 2016 with the FSQ telescope and the QHY90A CCD.

It is a relatively faint emission nebula in Cepheus. Sometimes calledo as the “Flying Bat” nebula, this region is characterized by Hydrogen emission. Inside it we found the recent discovery made in 2011 by Nicolas Outters, called the “Squid Nebula” due to its shape, but more officially called Ou4. This region is characterized by a very faint OIII emission and its bipolar shape reminds of a planetary nebula. Covering our image only the Ha range the Ou4 is invisible.
