M 17 in Sagittarius: A View in Narrow Band Mapped in HST Pallete - Now With Image_Rev-D -

M 17 is distant 17 thousands light years from us and shines thanks to an embedded open cluster formed by about 35 stars made by material of the nebula.

This view used the HST pallet to map the captures of Ha, O3 and S2 in green, blue and red, respectively.

As we can see, there are areas with all three materials mixed, but most of the nebula is formed by Ha.

The stackup for this image is:

Ha, S2 and O3: 7x20m for each channel

Bias, darks and Flats applied.

Pre-Processing and Post-Processing in PixInsight

** Re-processing: I captured a couple of extra subs what allowed me to push some more details of the shock wave present, in addition to do a post-processing less agressive. I hope you enjoy the new image. **

*** A Note on Image_Rev-C: A new color mapping has been used, as well as, some contrast and sharpening has been pushed using multi-dimensional processing.

When you are going to see this image, choose Full Resolution from the drop box on the upper right corner of the image's frame. I think It's worth that view.

Please fell free to drop a line of comment about this new release, even for saying that you don't like it.

**** A Note on =REV-D= A new reprocessing has been done using some new resources of PI. Also a new new white balance has been introduced, aiming to eliminate false colors and artfacts present in previous versions. I hope you like this new version.

Thank you

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.
