IC 1805, the Heart of the Heart

I last attempted the heart nebula when I first got into astrophotography a few years ago. I used a DSLR on that occasion, and I didn't know much about processing. Thanks to a stretch of good weather this November, I was able to collect a lot of good narrowband data. (The RGB data was used exclusively for star replacement.) I had a great time processing this one because there was so much background detail that I wanted to bring out.

If anyone knows what that blue oval doodad is along the left lower edge of the image, I'd be delighted to hear from you. I suspect it is a planetary nebula but cannot identify it. I did see it in other people's images, so I know it is not a glitch in my data.

UPDATE:
Thanks to my good friend, Eric Dreher, for identifying the planetary nebula as WeBo 1 (PN G135.6+01.0). There’s an interesting article about it in the Astronomical Journal.

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.
