NGC 6559 The Chinese Dragon in Sagittarius in Narrow Band

NGC 6559 is a star-forming region abundant with collpasing Hidrogen, but also made from particles of dust, made of heavier elements, such as carbon, iron or silicon.
It is located at a distance of about 5000 light-years from Earth, in the constellation of Sagittarius, not far from it's more famous neighbour, M8, the Lagoon Nebula. It shows both emission (red) and reflection (bluish) regions surrounded by with dense regions of dust that completely block the light from behind it (Barnard 302 and 303) and numerous HII regions .
Size is around 15 x 10 arcminutres.

The is all new NB data collected in Late June and early July under a blazing moon and with wildly variable seeing conditions before the weather turned to rubbish. I was hoping to get more but you can't always get what you want. I've mosaiced this area before and it will be close to the top of my list for a wider field scope like a Redcat 71, under darker skies. M8, M20 and NGC 6559 in one field. What more could you ask for. For now I would settle for the rain to stop.

Addendum: Astroimaging really is all about going the extra yard. With a promising forecast last night I got setup under clearish sky only to be smitten by cloud so I waited, and waited and then packed up.
Sure enough that did the trick and it cleared magicallly. As there was no wind I just flipped the pump shed lid open and went for it without the elaborate dew and wind shields . I managed a pretty good extra run with good seeing. The payoff was now there was enough data for ESD Integration and that makes quite a difference.

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.
