Fluorescence

"Fluorescence - the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation"

Deep in the heart of the Namibian Great Escarpment lies the Gamsberg mountain range. Concealed in a valley amidst the Gamsberg foothills is the Rooisand Desert Ranch, named for the ancient windblown Kalahari desert sand that renders vivid red tones across its plains.

This is a 56 panel panorama of the night sky shot from the far western end of the Rooisand runway on May 19th 2023. Commencing at 01:46 when the core of the galactic plane was approaching the meridian.

Shot with dual Sigma Art 28mm f/1.4 DG HSM lenses, a modded Canon 6D MKII for the RGB sky and land signal and a modded Canon 6D with Astronomik 12nm Hydrogen-Alpha clip in filter for the 656nm emission line.

RGB sky exposures - 40 x 1 minute at f/2.0 ISO 1600 - 5 rows 8 columns
H-Alpha sky exposures - 40 x 1 minute at f/1.4 ISO 3200 - 5 rows 8 columns
Land exposures - 5 x 1 minute stacks at f/2.0 ISO 1600 - 2 rows 8 columns

The revised render does not include the H-Alpha data to better preserve the true magenta tones and is a generally less intense 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.
