M42 - Orion Nebula (Scott Badger)

M42 - Orion Nebula

Revision Note:
Been playing with new tools and old data, and this is the oldest……first of all lights, first image on my new first telescope. The data is thin, less than an hour, unmodified DSLR, no autoguiding, and out of focus…..not to mention blown out around the trapezium area, but since it was my first target, and one of the coolest DSO’s in the sky, imo, but more difficult to image from my new observatory location, I wanted to make any improvements possible with what I have, as little as it is. Anyhow, wasn’t able to do much about the blown out area, and surrounding it is still really flat looking, but BlurX did a great job with the stars and dealing with the focus/seeing issue. I also added a very light touch of unsharp mask sharpening to a synthetic luminance. And actually seemed to have even gained a little experience, at least in dealing with the background color gradient : )
---------------------------------------------------------------------------------------------------------------------------------

First DSO image using my own gear. The subs are 20s exposures at iso 1600, though next time I think dropping the iso to 800 and maybe 30s exposures might be better for that little bit extra dynamic range. I also shot at 15s/3200 iso but the Trapezium area was pretty blown out. I tried an HDR combination of the two sets, but ended up with a distinct ‘bib’ like effect in that area. Not sure if it was bad data, or datatician….. Anyhow, I did use the HDR version to create a synthetic luminance and added it to this integration which brought out a lot of detail.

Description: Before I started working on this image, I stretched one of the subs in LR to see what I was working with. It showed vivid pink and teal and, so, that was my expectation as I processed. The pink showed pretty much as expected, but the teal was much more blue and I found myself working hard to push the image where I thought it was supposed to go. In the end, I was sort of successful, but felt it looked over worked (since it was!..) and what first submitted was my attempt to bring it back to something more natural. But that was just more processing on top of too much, so this revision is starting over from pre-color calibration.

Regarding the teal in the single sub, gven the no-green-in-space mantra, is that green noise mixing with the blue?

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.
