M78 - Reflection and Dark Nebula

Revision title: Reprocess with Topaz

Lots of interesting things going on here. M78 is a bright reflection nebula, but some of the light is obscured by a dark cloud of dust. The bright spots in the dark region on the left are Herbig–Haro objects, which are narrow jets of ionised gas. One of these is HH24, the subject of one of the most amazing photos taken by Hubble. It's just a little smudge of light here unfortunately.

I normally set the background a bit darker than this, but decided to make an exception here to better show the dark cloud against the rest of the sky. Spooky.

Title: Slightly brighter

Description: For some reason images seem darker when viewed in a browser than in Photoshop or the image preview app, so adding a slightly brighter revision.

Title: Reprocess with Topaz

Description: I was never quite happy with the noise levels in the prior versions, so I finally decided to take a quick reprocess with Topaz in the workflow. It was not quite the improvement I was expecting, but it was marginally better with a lot less effort than I put into it before.

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.
