I took this image from my local astronomy club dark site. This is an attempt at an HDR version of Orion, a combination of 50x300s & 50x30s lights. Unfortunately, I was unable to figure out how to stretch the image while preserving the distinct stars within the trapezium. I'd like to come back to this data when I have more time and attempt another pass at combining the two sets of lights and preserve those stars. Tips and criticism appreciated!

Subs: 50x300s/50x30s Lights; 0 Darks; 40 Flats; 200 Bias

Processed in Pixinsight & Photoshop. Photoshop was only used to manually paint out some star cores I accidentally blew out.

Process:

• Manually stacked in Pixinsight

• AutomaticBackgroundExtractor

• BackgroundNeutralization

• ColorCalibration

• HDR Composition (I couldn't find the best time to combine the two sets, is this an appropriate spot?)

• Deconvolution with Dynamic PSF

• SCNR

• TGVDenoise

• MultiscaleMedianTransform Denoise

• Resample

• Arcsinstretch + HistogramTransform (Combined 50/50 using pixelmath)

• CurvesTransform

• ACDCNR

• MultiScale Linear Transform Denoise & Sharpening

• MorphologicalTransform for shrinking stars

• Unsharp Mask

• DarkStructureEnhance

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.
