NGC 6188 Mapped in HST: New Narrow Band Data Blend Processing

This emission nebula is found near the edge of a large molecular cloud unseen at visible wavelengths, in the southern constellation Ara. New stars were formed in that region only a few million years ago, sculpting the dark shapes and powering the nebular glow with stellar winds and intense ultraviolet radiation.

The recent star formation itself was likely triggered by winds and supernova explosions, from previous generations of massive stars, that swept up and compressed the molecular gas. Joining NGC 6188 on this cosmic canvas is rare emission nebula NGC 6164, also created by one of the region’s massive O-type stars. This nebula is distant 4.000 light years and comprises of a planetary nebula, just barely visible in this image (on hte lower left hand) and some patches of dark nebulas.

This data is the same posted before, the difference is the way that the narrow band data has been blend. In short, the method proposed by J-P Metsavainio has been adapted to use PixeInsight as the image processing platform instead of Photoshop.

Metsavainio's method in my opinion is very cleaver in all points and in the end produces an image smooth, sharp and very close to the final color mapping, needing just some minor tweaks. Thereby I should say thanks to Mr. Metsavainio for sharing his outstanding tutorial.

Please note that all the imperfections in the previous image, like star shape, remain in this version. However the quality of the rendition, still in my opinion, is very superior in this later version..

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.
