LDN 1152 (The Architeuthis Or Giant Squid In Draco Cepheus)

LDN 1152,RNO 124 (" The Architeuthis Rex or Giant Squid ".This was my first impression when processing the image. An Architeuthis Rex expelling ink all around )

RNO 124 :As a whole, this nebula has a conical shape, with a star IRAS 20359+6745 at its apex. It is possible to separate two distinct reflection structures in the nebula. The former is represented by a regular cone with an opening angle of about 60 degrees and with straight walls, which are extended up to 2´.

Observations confirm that RNO 124 is a system with directed outflow, which produces HH 376A as well as forms the

cone reflection nebula with traces of two probable helical arms. The Ha line in the spectrum of the source star shows the presence of a high

velocity component, associated with the collimated flow.HH 376A is the bow shock structure in the collimated high velocity flow, directed by the axis of the cone nebula, with shock velocity about 70-80 km s-1.

L1152 is a Lynds Opacity Class 5 cloud located in Cepheus (Lynds 1962), at an assumed distance of 325 pc (see Kirk et al. 2009).

Stars form as a result of the gravitational collapse of clouds of gas and dust. This process can take place in isolated Bok globules or within fragmented giant molecular clouds . The earliest recognizable phase of the star formation process is the Class 0 phase (Andre et al. 1993), the beginning of which is marked by the formation of a hydrostatically supported protostar within an infalling cloud of gas and dust.
