Revision title: Topaz "enhanced" image of the original version.

I obtained the ZWO 54mm filter drawer for my 0.72 reducer of my FLT 132 and once I finished all my current projects with the reducer I flipped over to the new setup. Of course finding the correct back focus was a challenge, took me some time (always hard to skip some clear skies ... hurts 😊), still not perfect, but I was happy with the results after some hours.
With the reducer, I wanted to target several objects that need the extended FoV, and for sure the Heart Nebula was one of them. My previous trials were not that great, hence I needed to target it anyway one day. I checked the size and found the correct orientation to get the whole nebula without any mosaics, which I definitely prefer (saves many many hours)!
I tried to keep it as "natural" as possible (if you can say that at all with an SHO image), no exaggerated color boosting (I am just not a fan of it) and moderate sharpening.
The green channel plays quite a role at the end, 2 more examples as Version B and C with slight variations of it.

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.
