Heart Nebula and WeBo 1 planetary nebula at 43MP

Revision title: Pushed contrast

This image may look like a regular Heart Nebula, but it also contains a very interesting object WeBo 1 at the top of the image - it looks like a little blue Saturn.
This object is barely visible on most of the images of the area, but I was able to bring it up in processing.
I noticed it while processing the image and thought that it was some kind of artifact, so started going through the stacked channels and individual frames and it was right there.
Then I started looking through other images of the area and saw that most of the images were also showing it there, but only vaguely.

WeBo 1 is a young barium star surrounded by a ringlike planetary nebula and was only recently recognized.
It has a remarkable thin-ring morphology, was discovered serendipitously on Digitized Sky Survey images. The central star is found to be a late-type giant with overabundances of carbon and s-process elements. The giant is chromospherically active and photometrically variable, with a probable period of 4.7 days; this suggests that the star is spotted, and that 4.7 days is its rotation period.

This image was sitting in my staging area for longer than a year because I did not like the colors and stars were too much undersampled.
I had to do a full reprocessing of this data, starting from stacking with drizzle 2, to give this data justice. With drizzle 2, the resolution of this image is equivalent to a 4 panel mosaic, taken with a ~750mm telescope.

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.
