Sh2-207 & Sh2-208

This object is a pair of HII regions located in the constellation of Camelopardalis at a declination of +53 degrees.

SH2-207 is the large HII region at image center. This region lies 15000 light years away. It spans 4.5 arc-minutes in our apparent view, which corresponds to a width of 20 light years. This object is also classified as PK 151+02 1, which is the designation for a planetary nebulae, but it is now known that this object is a HII region. The open star cluster in the upper half of this object is Mayer 2.

Sh2-208 is the small HII region at right. This region contains the open star cluster GSC 03719-00517. This region lies 13000 light years away. It spans 1 arc-minute in our apparent view, which corresponds to a width of 4 light years.

Faint dust and emission fills the background and obscures the stars to some extent. A more distinct band of emission is seen on the right edge of the image above Sh2-208.

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.
