Sh2-207 / Sh2-208 (Eddie Bagwell)

Sh2-207 / Sh2-208

Two Sharpless targets in this frame from the Constellation Camelopardalis.
Sh2-207 is the larger Nebula on the right and the smaller one to its left is Sh2-208.

1959 - While searching the photo plates of the Palomar Observatory Sky Survey made with the 48-inch Schmidt telescope, the American astronomer Stewart Sharpless came across the two emission nebulae Sh 2-207 and Sh 2-208 and published them in 1959 together with a total of 313 H-II Regions in his catalog.

1961 - The Soviet astronomer Boris Aleksandrovich Vorontsov-Velyaminov suggested that the faint, round nebula (Sh 2-207) could be a typical type IIIb planetary nebula because of the well-defined ring structure.

1967 - Two Czech astronomers Luboš Perek and Luboš Kohoutek listed the nebula in their Catalogue of Galactic Planetary Nebulae under the designation PK 151+2.1.

1976 - Spectroscopic studies showed that Sh 2-207 is more of an H-II region.

2000 - It is reissued as a misclassified PN and probable H-II region.

Present - Sharpless 2-207 is a star-forming region, similar to a miniature version of the Rosette Nebula. The age of the star cluster located in the western part of the nebula has been estimated at about 2-3 million years. The smaller H-II region Sharpless 2-208 is at about the same distance.

Thanks, Eddie

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.
