LBN 673

This object is located 6500 light years away in the constellation of Cassiopeia. This is an amazing complex, including emission nebulae, star clusters, dark nebulae, and fantastically eroded dust pillar towers.

There is a surprising amount of confusion in the literature for the designation of this beautiful area. Even Astrobin has the incorrect designation shown on my image above. This object is neither IC 1871 (which is a cluster off image to the left) or IC 1848 (which is a cluster off image to the right). The best that I can determine, the bright nebula at right center is LBN 673. The cluster to the left center is Collinder 34. I cannot find the designation for the cluster near the right center edge of the image.

I love how the clusters, centered in the bluish (oxygen) areas, are eroding and sculpting the massive dust clouds into a series of huge towering pillars. All of these pillars are pointing back towards the clusters. I also love the beautiful backlit glowing edges of these pillars. Each pillar spans about 10 light years. The stately pillar at lower right is amazing - a mountainous orangish pillar topped with a white majestic extension, like a lighthouse on a pillar of rock.

The dark silhouetted cloud shapes are also beautiful. I especially like the dark spider-web-like netting of dark nebulae at upper left, and the intensely dark irregularly shaped small patch at center right. I can't imagine how dense this latter cloud must be to block out all of the bright light behind it.

The refractors!

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.
