So many wonderful images of M42 on AstroBin I felt I had to join in

Incredibly this is my first M42 since 2009 what!
The difficulty with M42 is the dynamic range, the inner core with the Trapezium is very bright whereas the outer portions are typically faint as most other nebulae. I took 5s exposures for the core and 30s exposures for the outer parts along with blending in Hydrogen alpha at 30s also. I used Affinity Photo for the layers as Pixinsight just didn't seem to give a good finished blend, maybe my lack of skills. Anyhow I'm pleased with the result for now, next year a deeper image.

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.
