The Dark Tower

Dark Tower Nebula in Ha, Sii, and Oiii FiltersThe Dark Tower Nebula, a striking region of cosmic intrigue, is captured here in stunning detail through the Ha (Hydrogen-alpha), Sii (Sulfur II), and Oiii (Oxygen III) filters. Located near the constellation of Scorpius, this nebula is a prominent feature within the Lagoon Nebula region.This image reveals the intricate structure of the Dark Tower Nebula, with its dense columns of gas and dust that obscure the light from newly forming stars within. The Ha filter highlights the glowing hydrogen gas, creating a vibrant backdrop against which the dark, tower-like silhouette stands out. The Sii filter accentuates the regions rich in sulfur emissions, adding depth and complexity to the image. The Oiii filter brings out the oxygen emissions, often seen as a bluish hue, highlighting the areas of high-energy activity.Together, these filters provide a comprehensive view of the nebula's composition and the dynamic processes at play.

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.
