The Elephant's Trunk Nebula in HOO with RGB stars. I think this is my longest integration so far with hover 20h of exposure time between 5 nights.

I wanted to have a more natural look so went with the bi-color palette Ha and Oiii. The Ha, which had a really strong signal and details, was used as luminance. As for the stars I extracted the Hue from the RGB and integrated them in the final image. Very happy with the final result although would be best having more exposure time with the RGB stars.

Acquisition:
122x300s Ha
103x300s Oiii
10x240s Red
10x240s Green
10x240s Blue

60 Flats for each filter
60 Darks (master dark library)
60 Bias (master bias library)

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.
