WR134

WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun.

Intense radiation and stellar winds have created a bubble of gas around the star. In this image the bubble is seen in blue doubly ionized oxygen light. When i was imaging the OIII data I noticed when i did a very aggressive stretch on a single frame that there is a lot more OIII signal in the area. Once I saw this and that is actually might have some texture to it, I decided to integrate many more frames into the stack. Finishing at 100x10' frames I was able to pull out a significant OIII signal from the stacked image. As you can see the OIII signal extends well beyond the main OIII emissions. The faint OIII has some texture, ridges, and wispy elements that add a lot to the image. I am glad I was able to see the faint OIII and subsequently capture many more frames to bring it out in its fullest.

I went a little less aggressive with this image in regards to star reduction. I typically drop the stars down significantly to bring more focus to the nebulosity, but this time I left them more pronounced. Which do you prefer, heavy or light star de-emphasis?

Thanks for looking

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.
