Molecular Clouds near South Pole

A first attempt at imaging portions of the delicate molecular clouds visible near the South Pole.

This region in Octans was selected after browsing through Nina's offline sky map cache and picking an area that seemed to combine interesting structure with some nicely contrasting colourful stars - not very scientific I know! I'm not sure if this object has an official designation (I can't find one) - please let me know in the comments if so.

Unwanted gradients were a challenge. I ended up writing some software to estimate the RGB pedestal levels on a grid, smoothly interpolating between the grid points and then subtracting from the final image.

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.
