Sharpless-308 The Dolphin Nebula in widefield HOO

This is Project 2122 started Dec 30 and completed acquisition last night (Jan 7) for an extra full 6hrs bringing it to a total of 25hrs integration time. The nebula surrounding the bubble did get denser as did the starfield. I think the amount of time spent has done it some justice. I did have to crop around the edges somewhat to remove stacking artefacts introduced due to the long period of imaging.
Also, cooling temp was not consistent throughout as I had to bump it up one night due to higher ambient temperatures. Didn't seem to affect the calibration using existing dark subs. I used the Ha layer as a luminosity layer but because of the increased density of the starfield, I had to use some starnet + tone mapping to enhance the bubble nebula.

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.
