The Hunter's Belly - Orion Nebula, M 42, NGC 1980, NGC 1999, (Georg G Albrecht)

The Hunter's Belly - Orion Nebula, M 42, NGC 1980, NGC 1999,

This data has been sitting around now for a while. I did the first processing back in November for our Discord's group monthly_pics. The HDRComposition tool in PixInsight did give me some trouble in combining the 5, 30, 120 sec L-Pro subs with the 300 secs subs taken with the Antlia ALP-T filter. I remember staying up the whole night working with my friend over our Discord chat live on the PixInsight project trying every possible way until HDR accepted to combine the 4 images. I finalized that image the next day. And I knew then it could be done better... So today I tried again. The same happened and it just didn't want to combine, no matter to which of the 4 images I was doing a linear fit. So, I decided to combine the 5, 30 and 120 sec images together with HDR and that image I combined again in HDR with the 300 sec sub... And it worked. And it came out better then the first try in November. Once I had the combined HDR image I used BlurXTerminator on it just to see if it would work. And it did. The rest was NoiseXT, Histogram Transformation, StarXT, some curve adjustments combined with a few masks, some Local Histogram Equalization and star recombination. Done! Although, there are a few things I need to address later...

Our November challenge was anything in the Orion constellation and I was drawn between imaging the Monkey Head Nebula or the Lower's Nebula or maybe some reflection Nebula. But then I cam across an interesting reading about NGC 1999, particularly it's dark spot on the nebula. Apparently after long believes of it being a dark gas region obscuring the view, it turned out to be just the opposite, an opening into the un-endless deep space... No surprise there, did I want to know if I could capture that little speckle with my guiding scope turned imaging scope.

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.
