Widefield of Eta Carinae Nebula Region

A (kind of) old image, with a very short integration time on a beautiful southern target - NGC 3372 or the Carina Nebula.

I found this image to be extremely difficult to post-process,due to the short exposure time, the not-so-perfect tracking (stars not perfectly round), and the sheer amount of stars in the FoV, and I'm still not pleased with its colors, which were my main problem during processing. The data seems to be quite good, as well as the detail I captured (for a unmodded, stock canon APS-C DSLR) in the faint, red, H-alpha nebulosity. However, the image looks a bit overprocessed, and too HDR-like to my personal taste. It is a HDR of different stages on the processing, to show the core details.

All told I'm pleased with it, but I will give it a try at reprocessing when I have the time, only after having edited all the data from this holidays (July). Therefore, so far that's my version of it, but I would definitely call it "Version 1", instead of "Final Version". ; ) Constructive criticism and comments are always welcome. Clear skies!

Taken from Rural Skies (Bortle 3-4), in Rural Cristina, MG, Brazil. Thanks for seeing,

Camera: Unmodded T4i/650D at ISO 800

Lens: Tamron 70-200mm f/2.8 (non VC), at 200mm and f/3.5

Exposure Detail: 15x120s; or 12x2 minutes; total 30 minutes.

*Revision -C- is a simple crop from version -B-, on the most interesting region, the Eta Carinae Nebula itself. This is the frame of a tipically short APO, at about 500mm FF equiv.*

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.
