Southern Hemisphere Nightscape (Dean Carr)

Contains: Extremely wide field

Southern Hemisphere Nightscape

As an interlude between deep space imaging at the Wiruna dark sky site in rural NSW, Australia, I took the opportunity to do some nightscape photography after completion of the main observing event when most people had returned home.

This Nightscape (still) image utilized 21x13-second subframes (Total exposure 4 min 33 sec, spanning 4 min 54 sec), extracted from the night’s overall set of subframes.

The specific timeframe for the image was chosen to allow a reasonable framing of the Milky Way and two Magellanic Clouds. The Milky Way and foreground were processed to be somewhat subdued to avoid overpowering the overall appearance of the scene.

Processed using Nikon NX Studio, Sequator, and PixInsight.

General Concept

Three different products were developed from the same data - including Nightscape and Star Trails (still) images, as well as a Timelapse video. The idea was to use compromise exposure and other camera settings that enabled the production of all three products, albeit not necessarily ideal for any one of the products.

Images were taken using a Sigma 20mm f/1.4 lens on a Nikon D750 camera attached to a fixed tripod. In total, 2135x13-second subframes were taken with 14-second intervals at f/2 and ISO1600. Total overall exposure for the night was 7 hrs 42 min 35 sec, spanning 8 hrs 18 min 10 sec.

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.
