SL-17 The Dark Wolf Nebula

After months of clouds in Melbourne Australia, I finally managed to finish capturing and processing this image of SL-17, the second target that I have captured with my ASKAR 107PHQ. This dark nebula is located in the constellation of Scorpius and has an uncanny resemblance to a wolf and is know as the 'Dark Wolf' or 'Fenrir Nebula'. SL17 is situated in the emission nebula RCW113 (or Gum 55).

This nebula does not seem to get imaged too often. I originally planned on processing this image in SHO but I'm not liking the look of it with that palette so far... so I have settled on the HOO with RGB version for now.

One thing that I have done differently this time is to capture my stars with 30s exposure and gain 0 instead of my usual 15s gain 76. The result was much better star colours information when increasing the colour saturation on the stars during processing.

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.
