NGC 1973, 5, 7: Its Hidden Wonders

OTA: PW17
Camera: QHY 600
Observatory: Deep Sky West
Date of Capture: Dec '22
Date of Processing: Feb '24

Exposures Used:
R: 23 x 300 sec
G: 29 x "
B: 22 x "
L: 23 x "
Total Exposure time: 8 hours
Image Width: 40 arc-minutes

Processing Tools:
1.   Commercial: PixInsight, Topaz, Photo Director 365
2.   Pixinsight Addons: NoiseXTerminator, BlurXTerminator, StarXTerminator
3.   My Scripts: NB_Assistant, AC_Restar, Subframe Weighting Tool (Excel w/ J. Hunt), ColorTweaker

Target Description:
NGC 1973 is part of the Orion Nebula Complex. This is not an image I'd hang on the wall. For whatever reason, there is little detail and hence little to attract the eye and focus attention. Sad! There are numerous nearby nebulae that "out-shine" this one in wonder and beauty!

Processing Description:
This is the best of my two tries at post-processing this target. The processing was heavy, uncovering some detail that few other images of this target reveal.

Target Statistics:
Distance: 1500 ly
Apparent Magnitude: 7
Pixel Span at Target: 2.6B ly

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.
