PixInsight Processing for the Record:

1. Stack original .FITs images using Menu Script/Batch Processing/BatchPreprocessing

2. DynamicCrop

3. LinearFit

4. TGVDenoise (mild non-linear; more aggressive linear)

a. Strength reduce to -1 for linear; larger the more aggressive

i. Light 0.15; 0.05; 2.0; 500

ii. Chrom 7.00; 0.003; 2.0; 500

b. Edge Protection=SD of background (left more protective; right could lose structure)

c. Iterations 250->500

d. RGB same setting both CIE separate L versus C

e. Local support for linear, enable preview

5. CHANGE TO NON-LINEAR (STF->HT)

6. Masked Stretch

7. Deconvolute

a. Dynamic PSF

i. 50-80 stars

ii. Moffat only

iii. Save output image for use later

b. Star Mask

i. First Panel

1. 0.02 noise

2. 6 scale

ii. Next Panel (Structure Growth)

1. 2

2. 2

3. 3

iii. Next Panel (Mask Generation)

1. 16

2. Check Invert

c. Luminance Mask

i. Shadows moved just to left of first light

ii. Apply to image (Do not invert?)

d. Deconvolute itself

i. External PSF image file

ii. Algorithm Regularized

iii. Iterations 25-40

iv. Deringing Dark 0.01

v. Use star mask

8. Pixel math to creat RGB H=R; O=B;S=G

9. SCNR to get out GREEN

10. Colort Saturation adjustment

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.
