Paused and changed filters during live stack. Jumped straight to photoshop for processing. 32 subs is barely enough to provide texture in dark areas. Would be improved with another 32 subs(64 total)

A fiery cauldron of soup, bubbling with new stars. Its SH2-140.

Sh2-140 is a nebula rich with hydrogen that glows from the radiation of the surround stars. The nebula is located in the northern constellation Cepheus. The massive cloud is 2900 light years away in the next spiral arm of our own Milky Way.

I was curious about the bright center of this region...so I managed to get a bit closer tonight with stronger optics. But we still can't see through the dark cloud of gas. The cauldron keeps its secrets.

Whatever is behind there it is hyperactive at cranking out tons of these new stars. They seem to rise with regular frequency.

Observatories imaging infrared spectrums say there are about fifty young stars still to come from behind that cloud, in the lower-right corner of the closeup image. That would explain the glow on the edge of the cloud, as the stars behind make it take on a translucent quality.

Strange that such a spectacle is stuck with a simple catalog number. What would you have it named?

A bewitching brew and a harbinger of the coming fall season. A good time to put on Bill Evans Trio's take on the song Witchcraft.

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.
