WR-134 and Nebula

Wolf-Rayet stars are extremely hot, bright, massive stars, and one of the rarest classes of stars known. As of 2018, only 154 had been identified in the Milky Way. Some produce spectacular nebula -- e.g. the Bubble nebula, and the Crescent nebula -- thanks to their strong stellar winds, intense ultraviolet emissions, and clouds of gasses that they shed in earlier stages of their relatively brief lives.

Back in July, I captured a spectrogram of WR-134 -- the bright white star near the center of the frame -- and two other Wolf-Rayets in Cygnus, and saw that a few other people had captured a graceful nebula surrounding it. So, here is my capture of WR-134's nebula, in HOO pallet with RGB stars. WR-134 is about 6000 light-years distant. Five times the diameter of our sun, it is 400,000 times more luminous, with a surface temperature of over 60,000 degrees celsius. With the stars removed, it becomes more evident that the O-iii extends in an iris-like ring around the central star. I'll need to revisit this next summer with a 3nm O-iii filter.

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.
