Sadr Region SHO Test

First light on my ZWO-ASI1600MM-P - and a testament to not only the quality of a cooled sensor, but the minimal amount of exposure needed for a decent image

Stacking:

- Ha, Oiii, and Sii Lights stacked in DSS using 100x Master Dark created in PixnInsight

PixInsight:

- Linear fit to Oiii channel

- Deconvolution with artifical PSF on the Ha channel

- TGV NR using Luminance mask for each

- MMT NR for each using Luminance mask

- Crop on Ha image followed by Star Align for the Oiii and Sii channels for alignment to Ha image

- LRGB combination to combined into SHO with Ha as Luminance

Photoshop:

- Copied image and turned B/W for Luminance edits

- Created 128, 128, 128 flat field and divided image into it to even out gradient (took no Flats)

- Reintroduced Luminance into color image

- Carboni's tools for Space NR and Deep Space NR, using Luminance masks

- Local Contrast Enhancement using star mask to enhance nebula detail

- Color edits to turn Green to Yellow, creating the golden SHO appearance

- Star Reduction using star mask

- Curves edits for contrast

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.
