Dolphin Nebula SH2-308 HOO + RGB Stars

I started acquiring data for this project back in September, after some time away and some average weather I finished gathering the data in Early November 2023.

Its early in the season for this target however with the shorter nights here in The Australian Summer the amount of data you can get at the perfect time for this object doesn't really change from spring. I used the HOO image palette with a bit of HA in the Blue channel.
Acquired RGB stars early November when the moon wasn't up.

SH2-308, the Dolphin nebula is ~4500 light years away and was formed when the main WR star EZ Canis Majoris star shed its outer layer some 70000 years ago. Eventually the str with go supernova and destroy the 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.
