ESO-378-1: A Rare Planetary Nebula in HOO with RGB stars

ESO 378-1 is a rarely imaged bubble type planetary nebula 2000 light years away in Hydra.
The bubble is quite symmetric as it continues to expand around a collapsing dying star shedding its gas layers.
This is 4 light years across and its type lasts for a short time on a cosmic scale existing for several tens of thousands of years before its gases disperse and fade away.
Imaged in Ha and O III and RGB stars on the Planewave CDK 700 at Observatorio El Sauce, Chile.
Image Preprocessing: Mike SelbyProcessed by me in Pixinsight and Photoshop. The Ha was masked by the stronger OIII and I had to blend back a stronger mix.

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.
