IC 1747 (Holepunch Planetary Nebula)

IC 1747 is a Planetary Nebula in the Cassiopeia constellation. IC 1747 is situated close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere.

Riedel Rudolf has a nice RGB image and encouraged me to try this object.

Another fine RGB rendition by Gary Imm looks different from the NB with the O-III externally. Do not think this is an artifact since all the stars are correct and they are dual band stars. The detail is all from the H-alpha which came out well using HDMRT at level 3 (after testing all levels 1-10). No AI, just PI.

Here is the H-alpha detail (drizzled) followed by the O-III, same HDRMT:

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.
