M42 - First light of my RedCat and ASI533MC Pro

The one and only Great Orion Nebula, the first target of my new RedCat and cooled astro camera. Spent a few nights learning the ins and outs of my new equipment and battling against wind, moonlight, and dithering mistakes, as well as learning different methods for HDR composition. In the end I've thrown out a few hundred exposures of varying lengths for one reason or another, but what's left I think works pretty well.

I would love some constructive feedback on processing tips. I think I got the core definition alright (without it looking unnatural), but I know my stars are huge. Going to experiment a bit more and hopefully post a revision in the next few days.

Cheers from NZ and Merry Christmas all!

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.
