SH2-308 Dolphin Head Nebula

This is SH2-308, in Canis Major, sometimes called the Dolphin-Head Nebula, a huge cosmic bubble blown from a huge Wolf-Rayet star in the center of the dolphin which is likely to go supernova in the future. The star has ejected material which creates the very faint ionized oxygen blue green bubble. It includes 19 hours of exposures combining 9 hours with an 80mm APO and the ASI294MC PRO from 2022 with 10 hours of exposures with an AT115EDT and an ASI2600MC PRO from 2023 from a Bortle 7 suburban sky, processed in APP and PS.

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.
