SH2-132 in HOO (Miguel A.)

SH2-132 in HOO

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

First night running 3 widefield scopes.

Object for the night was, the Lion Nebula, Sh2-132 is a large emission nebula visible in the constellation Cepheus. It is located on the southern edge of the constellation, a short distance from the boundary with the Lizard, along the plane of the Milky Way; the best period for its observation in the evening sky falls between July and December and is greatly facilitated for observers located in the northern hemisphere regions of Earth. Sh2-132 is located at a distance of nearly 3200 parsecs (almost 10400 light-years), thus placing it within the Perseus Arm, in the region of Cepheus OB1, a large and bright OB association. The stars responsible for the ionization of its gas are very hot and massive; in particular, two Wolf-Rayet stars have been identified, known as HD 211564 and HD 211853 (the latter also having the abbreviation WR 153), as well as a spectral class O8.5V star and about ten B-class stars. Around the O-class star and one of the Wolf-Rayet stars extends a bubble clearly visible in the radio wave band, identified as Shell B, probably originating from the stellar wind of the two massive stars. A similar but smaller structure, Shell A, hosts a K-class star near its center. Chain star formation processes are believed to have taken place in the nebula in the past; currently, these processes appear to be suspended since there is no evidence of recent activity. Nine sources of infrared radiation and a maser with H2O emissions have been detected in the direction of the nebula.

I imaged this object in early November. One night I was used 3 rigs., a first for me. The setup went really well. Took about 35 minutes to get all 3 imaging the object. Seeing was not the greatest.

Processing this object to get accurate colors in Hydrogen Alpha and Oxygen was a little challenging.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
