Robin's Egg Nebula - HOORGB Composition

Happy New Year everyone and clear skies in 2023!

NGC 1360 (aka Robin's Egg Nebula) is a planetary nebula situated in Fornax. The central star is actually a binary system (not resolved on this image) and according to Wikipedia this was only confirmed in 2017, so the white dwarf must be difficult to observe. This distance was measured between 1140 l.y. to 1790 l.y.

I find this object very unusual and interesting, given the fuzzy predominance of the OIII clouds and emission. It was shot with the 1m RC from Chilescope. It's a tough object to process and reveal its inner structure while keeping its glowing globular shape. No deconvolution or AI sharpening was used (the nebular structures are extended so the effect was minimal, except for the red Ha structure). I used a differential stretch for the stars without any reduction. This is a RGB composition, HOO enhanced, the two palettes are very similar and the OIII signal largely predominates.

R 7 x 300s
G 6 x 300s
B 7 x 300s
Ha 14 x 600s
OIII 14 x 600s

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.
