WR 134, a captivating member of the Wolf-Rayet star family, stands as a beacon of stellar grandeur in the cosmos. This massive and luminous star has shed its outer layers, creating a stellar wind that rushes into space, sculpting intricate patterns in the surrounding interstellar medium. Its fierce radiance and powerful emissions reveal the profound evolutionary processes occurring within its core.

WR 134 resides in the Cygnus constellation as a nitrogen-rich Wolf-Rayet star, belonging to a binary system. These massive stars are characterized by strong stellar winds that strip away their hydrogen envelopes, exposing their dense cores. WR 134's potent winds influence its binary companion and contribute to the galaxy's heavy element enrichment. As short-lived cosmic entities, Wolf-Rayet stars like WR 134 play a pivotal role in the stellar lifecycle, shaping interstellar environments and aiding in the creation of subsequent star generations.

WR 134 is a Wolf-Rayet star in Cygnus which is around 6,000 light years distant. It shines at 400,000 times the luminosity of 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/green doubly ionized oxygen (OIII) light. A large amount of hydrogen (HII) emission is also displayed as the red areas. The star responsible for this is near the center of the bubble and is whiteish. The image was taken with my #Stellarvue SVX 152T refractor and #zwoasi 6200 camera through RGB and HII/OIII filters. The image combines a bit over 47 hours of exposure time. Automation was controlled with a #primalucelab Eagle 4 pro and Voyager Astrophotography Automation software. The image is cropped and rotated for a pleasing view.

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.
