The image is built as an HOO with RGB stars and it was captured at Barcarena, Portugal (Bortle 8) in July 2023. As usual, struggled a lot with Oiii data, as it showed some gradients complicated to remove - still today I am unsure if it is properly modeled. On the other side, it was my first attempt to obtain a "natural" HOO, as usually I employ orange/golden tones for the hydrogen - I am fairly happy but still not sure if it is the right tone, or at least the one I have in my mind. Truth to be told, I really enjoy RGB tones but from my light polluted sky obtaining good quality data for it is close to impossible.

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.
