Sh 2-1 and vdB 99

This image FOV containing faint reflection and emission nebulae is located in the constellation of Scorpius at a declination of -26 degrees.

The brightest star in the image is the bright blue 2.9 magnitude star Pi Scorpii, located about 600 light years away. The blue reflection nebula immediately surrounding this star is vdB 99, one of the less spectacular objects in the vdB catalogue.

The broader area of nebulosity around this star, including the faint red Ha nebulosity near image center, is Sharpless 2-1, the first object in the Sharpless Catalogue.

As seen in the mouseover, this region also contains 4 designated bright nebulae - LBN 1092 to LBN 1095.

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.
