SH2-308 The Dolphin

So here we have the last image in my queue of the work I did with this FRA400. I had really hoped to find the time to double the integration time on this one but strangely, we have not had the usual great weather here in Arizona these last months and with the pandemic on the wan, I have been busy in my job as well. The result is an image that is not what I had envisioned, primarily because I don't think sufficient integration was done to swamp the noise and build signal. When processing this, I tried to be mindful of that and "take what the data will support" and not try to force more out of it than what is there. Consequently, I really tried to take the less is more approach to the processing and the result is, I think, ok considering the circumstances.

This beautiful nebula in Canis Major, located about anywhere between 1,875 and 5,870 light years away (depending on who you ask) is powered by a Wolf-Rayet star, EZ Canis Majoris. This is one, 23 times the mass of our sun, is one of the ten brightest Wolf-Rayet stars visible to us and varies in magnitude between 6.71 and 6.95 over a period just shy of 4-days. Some theorize that it could be a binary with a neutron star as a companion. Very exotic, that's for sure...

Anyway, I hope you like it, Clear Skies and of course, comments/criticism always welcome.

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.
