I've spent a lot of time looking at this data and every time I touch it something new comes out that I like more than the last time. I think I'm at the end of processing for now and am ready to move on. The next step for this image is physical media as it's intended as present.

B

Description: Little more data, a lot more processing tweaks. Most interesting was to align R to G and B by raising mid-tone. This made the image very interesting without introducing a false palette.

Uploaded: ...

C

Description: No new data yet but much different processing, especially around denoise. Probably too much as I lost some of the details in dark structures. Another go at this will happen and I'll try to preserve them better, especially with more data!

Uploaded: ...

D

Description: More NB data and messing with process, including a lot of playing with masks and color at the end. Tried Ha as L this time and used a pedestal in calibration. Didn't denoise RGB before LRGBC. Added a pass of DarkStructureEnhance as a final step as well. Need to work on the stars some!

Uploaded: ...

E

Description: Trying a sort of OOH blend. Reduced stars at the end then desaturated them to bring them back into the background better. Still colors are off on stars but it's OK.

Uploaded: ...

F

Description: Finally might call this done. Spent a lot of time with color masks and manipulating things at various stages of processing. Also with removing stars then adding back in. The stars are the only bit taken from RGB data and they're true colors which is a nice change from previous versions.

Uploaded: ...

G

Description: Total revamp using better process and tools. Went with the colors straight off the camera. Stars are RGB.

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.
