Dark Nebula Barnard 174 (B174) in Cepheus

Barnard 174 is a very dense dark nebula which absorbs the light of the stars behind the nebula. This dark nebula is found in the constellation Cepheus. Infrared observations show many young stars in this region. So, B174 is an active star forming region. Almost 6 hours of imaging was needed to bring out this dark area.

The astronomer Edward Emerson Barnard compiled a list of dark nebulae known as the Barnard Catalog of Dark Markings in the Sky, or the Barnard Catalog for short. The nebulae listed by Barnard have become known as Barnard objects. A 1919 version of the catalog listed 182 nebulae; by the time of the posthumously published 1927 version, it listed 369.

Tech Specs: Sky-Watcher Esprit 120ED Telescope, ZWO ASI2600MC camera running at 0F, 340x60 seconds guided exposures, Sky-Watcher EQ6R-Pro pier mounted, ZWO EAF and ASIAir Pro, processed in DSS and PixInsight. Image Date: September 6, 2023. Location: The Dark Side Observatory (W59), Weatherly, PA, USA (Bortle Class 4).

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.
