Squid Nebula (SH2-129)

Photographing this fascinating object which was only discovered a decade or so ago, has proved to be quite a challenge because of the nebula's large size, faintness and location in a part of the sky to which I have limited access.

The Squid is unfortunately larger than the field of view covered by my Esprit 150 /ASI 533 MC colour camera combination so I have had to make a mosaic. Consequently the integration time is not applicable across the whole object.

The restricted view from the backyard means that I can only photograph the nebula in the late autumn which is frequently wet and cloudy here. It is often only possible to take a small number of subs during short periods of good weather, and is the reason why it has taken so many nights over several years to build up enough integration time.

As something a bit different, also included is an OIII only version which shows just the Squid without the background Ha clouds.

Needs more light plus some tinkering with the processing so is still work in progress!

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.
