KjPn8 in HO+RGB stars

Revision title: Less clipping but less Oiii presence

KjPn8 is a faint bipolar planetary nebula located in Cassiopea. Imagined during several days on november 2023 to get the even fainter and very interesting Oiii signal. It has a caracteristic hydrodynamic shockwave of H alpha and Oiii forming what it might be described as a croissant or a seashell . I used the script NBcouleurmapper in PixInsight to create the narrowband color image. RGB stars were rescreened from my picture of the Bubble nebulaA detalied study of its formation and dynamics can be found here: https://www.astroexplorer.org/details/10_1086_309122_fg1

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.
