Iconic M42 with OSC

What a beautiful hard to believe area, but what a bitch to process. I plan on a new version every year because I love it so and to see my progress. When I see it over and over again on this site I think to myself, “Who ordered that?” (quote from Isidor Isaac Rabi, Nobel-prize winning Hungarian-American physicist, on the discovery of the muon in 1934).

My goal this year in processing was to bring out the dust and still see the Trapezium stars and keep the core bright as it really is. I found really difficult to do both. I spent many nights trying different capture settings backyard...not achieving my dust goal. I did have one night on the new moon at Mercy Hot Springs, bortle 3/4, where most of the data is from. I used HDRComposion and ArcsinhStretch the first time. I processed from scratch 15 times give or take plus or minus. I am pleased with the result although I feel the color is off a bit even with PhotoMetricColorCal...there's always next year. I am also pleased with the performance of the WO 81GT even though slightly under sampled with the ASI2600MC.

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.
