NGC 6188 in Ara

After ten years of attempting to photograph this magnificent deep space object, I couldn't hold on any longer and had to share what I've done so far.

This is my first image in a year and my first attempt at narrowband processing.

NGC6188 mapped to the Hubble palette of sulphur II for red, hydrogen alpha for green and oxygen III for blue.

I still need to blend in the LRGB stars to get rid of the purple stars and replace them with natural colours.

This is 24 hours of data, 8 hours in each channel of hydrogen alpha, sulphur II and oxygen III, captured over 18 nights in June, July and August.

I hope you like what I've done thus far.

Comments, critique, lynching, etc., most welcome.

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.
