The Great Orion Nebula

There are many pictures of the Orion Nebula, but this one is mine.

We had our first (and only) clear night without heavy winds in months, so I got out to the farm and set up. I had to wing it on some of the gear (I switched from the NBZ to RGB, and took a guess at the spacing), it was super cold out so I couldn't sit and do a lot of adjustments, and I knew I only had the one night. I sat in my car trying to keep warm as the images rolled in, and just hoped the result would be worth it. Clouds rolled in at 2am.

My original plan was to use subframe selector and narrow down my image stack, but to start I went ahead and tossed every sub into image integration without review - the result was surprisingly good, so I ran with it and didn't bother with another integration. (I did use SFS weighting in WBPP with a focus on eccentricity and SNR)

Processed using some tricks I learned from Adam Block's videos when I processed my photo of the Iris Nebula, his blend technique is a great way to bring out the dust. Masked stretch and HDRMT kept the detail in the core, to what I think is a solid result.

I'm very happy to finally have an image of the Orion Nebula! Hope you enjoy it as much as I do!

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.
