This is my first picture with my new mount and second complete rig that I can run simultaneously to my original rig.

D

Description: I forgot to add in the Ha layer, lol. So, I reprocessed it all and found that it has a better HII region representation, but at the cost of some dust contrast. Overall, however, I like this version better.

E

Description: Forgot to crop it, reduce some remnant red in the background, and ran a blue/yellow S-curve after range-masking the core to correct the colors there.

Uploaded: ...

F

Description: I realized that I can recover some of the dust contrast by making a layer mask in GIMP with the extracted luminance from the first version and optimizing the opacity between the luminance layer and version D so that I can try to get the best of both worlds. I like this final version the best.

G

Description: I figured out that I can run ChannelExtraction and hit each monochrome sub-image with an HDR Wavelet and then recombine, fix color balance, denoise, sharpen, and presto.

Uploaded: ...

H

Description: I learned new techniques for manual stretching without blowing out stars and recovering better colors and detail from the main target. This isn't going to be the final version, but it is almost there.

Uploaded: ...

I

Description: Final version with new technique.

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.
