Dark Nebulae In Sagittarius (B92/B93)

This image includes objects listed in a number of well known astronomical catalogues including Barnard's; Sharpless; Messier; Lynd's and the New General Catalogue (NGC). Prominent in the centre of the image are the two dark nebulae Barnard 92 and 93 (a.k.a. LDN 323 and 327). These dark nebulae make for a nice contrasting feature against the backdrop of the busy starfield and pinkish glow that comes from the surrounding HII gas. Dark nebulae are dense clouds of dust that obscure the light from stars and objects behind creating the appearance of dark holes in space. The entire field captured in this image is encompassed in a large HII region catalogued as LBN 51 (Lynd's Bright Nebula) and Sharpless 2-41. According to the Sharpless Catalogue, SH2-41 is 3.5d x 2d which more than covers the field of view that we have here. The objects in this image are located in the constellation of Sagittarius along the plane of the Milky Way and include the "Small Sagittarius Star Cloud (Messier 24) which can be seen as the dense grouping of stars at the bottom of the image. The mouse overlay presents an annotated view showing the catalogued objects as identified by the Pixinsight render process.

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.
