Skull and Cross Bones Nebula (NGC2467 / Sh2-311) - A closer look

The Skull and Crossbones Nebula aka NGC 2467 / Sh2-311 is interesting because it is an active stellar nursery with a number of YSOs (Young Stellar Objects), with ages ranging from 1.2 million years old to the youngest a virtual newboarn at around only 2,000 years old!

The bright star at the center of the bowl shaped portion of the nebula (lower right) is HD 64315, an O6 star at magnitude 9.5 that belongs to the NGC 2467 open cluster, and is responsible for the ionization of this region of the nebula. The open clusters Haffner 18 and 19 are gravitationally linked as a double cluster and Wray 15-101 is a B-type star ionizing its immediate region.

Imaging note: This is my companion shot to the wide field capture posted using my technique for capturing using mulitpe scopes and cameras on one mount concurrently. On previous shots of using this technique, I had been using the Askar D1/D2 filters and swapping them between the two scopes/cameras about half way through the imaging run to get a similar set of data at different scales for the target. In this case however I didn't get the sense from my research that Sii signal was prominent, so I stayed with the D1 filter in the wide field shot for the whole run. So for the closer look through the TEC140 in this shot, I started with the Optolong L-Quad filter......but about half way through I though I needed more of a dual band filter's take on it (bses on what I was getting in the wide field shot) so I switched over to my older ZMO Duo dual band filter for the rest of the capture.

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.
