SH2-124 and lDu1 – PN G094.5-00.8a

SH2-124, located approximately 8500 light years away in the constellation Cygnus...and thats it. There is so little out there on this object I cant really tell you much more. It is a very faint object with good data in all three narrow band channels. It is pictured in sky atlas' as just a faint patch only highlighting the brighter circular nebulosity and ignoring the outer, very faint, shell gases.

I did notice a planetary nebula in the lower left of the image which at first I thought was a dust spec. After investigating that this "dust" spot only showed up in Ha and OIII I assumed I had a celestial object in the frame. After much research I found a paper, the same paper that announced the discovery of OU4 the squid nebula. This is a planetary nebula that is listed at a magnitude of 21.64 and is only visible in Ha and OIII. Very similar to the more famous soap bubble near the Crescent nebula. It was fun investigsting this object and for a few fleeting moments thought I may have discovered something new! I have cropped and added an image of the bubble as a revision.

Thanks for looking

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.
