Vulpecula OB1 is an OB association in which a batch of massive stars are being born.
It was first identified by W. W. Morgan et al.(1953)
In visual wavelengths, the OB association is linked to a star cluster catalogued as NGC6823.
This was discovered by William Herschel in 1785 and contains 50 to 100 stars.
A separate nebula, emitting visible light, catalogued as NGC6820, is also part of this multi-faceted star-forming region.
The association is located in the Orion Arm of our galaxy about 7,500 light-years away from the Sun.
Nebulae that are contained in this association include NGC6820 (Nebula - Mag 14.9) and NGC6823 (Cluster - Mag 7.1)
OB associations are young associations and contain 10 to 100 massive stars of spectral class O and B, and are known as OB associations.
In addition, these associations also contain hundreds or thousands of low and intermediate-mass stars.
Association members are believed to form within the same small volume inside a giant molecular cloud.

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.
