NGC 6309 Box Nebula Drizzle, HDRMT and AI Processing

The main story here is the processing. It was suggested by Pat Rodgers that I drizzle these small objects so that HDRMT and the AI might have more data with which to work.... a 2x2 wavelet becomes a 4x4 wavelet. Hope my math is straight.

Image 1 is not drizzled.

Image G is drizzled, some hint of core.

Image H has HDRMT applied

Image I final product after Topaz AI denoise and curves applied

Image K is my usual crop but only 1000x1000 pixels as the image scale is cut in half with the drizzling.... pixel scale should be about 0.6 Arc".

From Wikipedia:

NGC 6309, also known as the Box Nebula, is a planetary nebula located in the constellation Ophiuchus. It was discovered by the German astronomer Wilhelm Tempel in 1876. It has a luminosity of about 1800 times of the Sun. The distance to this nebula is not well known, but it is assumed to be about 6,500 light-years or 2,000 parsecs.

NGC 6309 is a quadrupolar nebula, with two pairs of lobes. Surrounding the pair is a spherical shell. The spherical shell formed before the four lobes.

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.
