WR 134 and the Ring Nebula - the power of progress! (Ivaylo Stoynov)

WR 134 and the Ring Nebula - the power of progress!

This is my second attempt at this target. The first one was 6 years ago, when it was a much more exotic project than now

Six years later the cameras and the software are much better and give more opportunities to explore the faint edges of the universe! Of course, the filters are of great help... I'm curious where we will be after another 6 years!

Here you can see the previous attempt - https://www.astrobin.com/316580/

The star Wolf-Rayet 134 (the brightest star in the center of the Ring Nebula) is a very hot star with temperature over 63,000 K and luminosity around 400,000 times than the Sun. Its radiation and very powerful winds are the reason to form the ring-shaped nebula in the mix of stellar matter and surrounding gas. Despite it looking like a planetary nebula, it is formed the same way as the Bubble nebula. Wolf-Rayet stars lose a huge part of their mass in stellar winds, which helps in creating the spectacular view. The distance from Earth is ~6000 ly and mass of WR 134 is considered as 18 solar masses, which combined with its super high temperature is putting it in the path of becoming a super-nova when it reaches the end of life...

WR 134 is one of the first three stars with unusual emission lines in the spectrum which lead to forming a new star's class - Wolf-Rayet stars.

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.
