It is uncommon to find high resolution color images of this rare planetary nebula called KjPn 8 .

Here then is another attempt at a narrowband object and like the previous I worked on (Squid Nebula, OU4)- this object is virtually equal in difficulty. I hope you enjoy seeing this, actually quite large PNe, zoomed in for perhaps the first time!

The Wikipedia page on this object (sans a *nice* color picture) is full of good information. It was likely formed by a binary star system in which each star died at nearly the same time to form this bipolar nebula. Note the inner bright hour-glass of one axis and the outer larger tubular form. There is even a tiny spiral like thing (center/core) where they share an envelope of gas. Based on measurements this object is around 4,000-5000 light years away and it has taken less than 10,000 years to do all of this
.
Special thanks to Josep Drudis for providing the OIII data.

P.S. The original data (Ha and RGB(stars)) has been on my machine for more than a decade (2011)). The addition of the OIII data plus my attempts at creating instructional videos motivated me to finally putting something together from this data (as I always intended to do).

Title: KjPn 8 (better contrast)

Description: I couldn't take it anymore. I think I made a major error. Although the reality is that this planetary has a very low contrast... I just needed to add more. So... this is it, my final "revision."

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.
