The Giant Squid Nebula

Revision title: Added more OIII and reprossed

Man this was a tough one to process. I took this over two nights (almost 8 hours of data), focusing pretty much just on OIII trying to capture the squid, but it is faint. I had to do several light stretches using star mask, then had to due some color select to try and pull out the blue. I have seen some really good images of this and I would rank mine as just in the OK category, I probably need a lot more data, which I might try to get. I pretty much just focused on bringing out the OIII and didn't do a lot with the Ha.

he Giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula. The Flying Bat refers to the Ha nebula, but I don't see a bat. Most experts estimate now that the Squid Nebula does lie inside the Ha Bat Nebula and is around 2,300 light years away.

Title: Added more OIII and reprossed

Description: Once again, I did not edit this as much as the first one. I didn't have to do as much to bring out the Squid. The squid is a little dimmer in this image, but if you zoom in and compare the two, I think this one looks more natural. Plus I just think the whole image and star field looks better.

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.
