This is the expanding bubble in Cygnus around Wolf-Rayet star 134 (WR134), about 6000 light years away, which is the second from the bottom of the four stars close to the center of the image.
The image was created from sixteen and one-half hours of exposures in July 2023 using an ASI2600MC camera, LX200 ACF OTA, ASAIR+, ASI174mm mini guide camera with ASI OAG, and an Antila ALP-T dual narrowband filter on an Ioptron CEM40 mount, processed with APP and PS.
