Squid Nebula and Flying Bat - 4 panel mosaic

Link: https://stevemilne.smugmug.com/Photos/Sky/Nebulae/i-nHw6Shw

The Squid Nebula is an extremely faint object thought to be around 2,300 light years away in the constellation of Cepheus and was discovered relatively recently (2011) by a French amateur astrophotographer named Nicolas Outters. It is catalogued as Outters 4, or Ou 4. It was initially thought that the Squid might be a planetary nebula, but this is no longer considered to be the case. The nature of the object is, at this time, unknown, although the ‘bipolar outflow’ is centred around the star cluster containing HR 8119 (Corradi et al, Astronomy and Astrophysics 570 - 2014).

The Squid is surrounded by the much brighter Flying Bat nebula (Sharpless 129) – a large emission nebula.

This is a 4 panel mosaic which was photographed between 21 August and 16 October 2020 using a rig in Spain that is privately owned and remotely operated by Barry Wilson and me. Back in 2017, I attempted the Squid using my widefield dual rig. I was able to accumulate a reasonable amount of OIII signal in 2017 and I decided to incorporate that into the new data.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

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.
