Crescent, Soap Bubble and WR-134 Shedding Their Layers

Space is not quiet or peaceful, only extremely large.

Here we have three stars explosively shedding their outer layers. The Crescent Nebula NGC6888, Soap Bubble Nebula PN G75.5+1.7, and my personal favourite, WR-134 are all pictured.

The Crescent nebula is quite popular, but the Soap Bubble and WR-134 are less so. Although they are all nearby, they require dark skies and far greater integration times to reveal. The Soap Bubble was discovered relatively recently by amateur astronomer Dave Jurassic in 2007. WR-134 is a faint bubble nebula of ionized gas created by the intense radiation and fast wind from the central star shedding its outer layers. The Crescent nebula is similar to these as it is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago.

This image consists of 25 hours of data taken over 7 nights in northern England and Scotland. 20 hours of bottle 4 subs with my ASI294MC Pro camera and Askar D1 Ha O3 6 nm filter, and 5 hours of O3 collected with a friend's ASI2600MM Pro and 3 nm Chrome filter. Detail in WR-134 was only possible with the mono camera in dark bottle 2 skies. This is by far by biggest project so far, requiring far more integration time than many brighter objects. Patience is key here given the classic English and Scottish weather!

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.
