Orion in HaRGB

The Orion nebula, M42 and M43 with a bit of a twist. This was a target of opportunity - my planned Ha target was too faint and too close to the almost full moon but I didn't want to waste a clear night as they have been pretty rare.
I wouldn't normally take RGB in these conditions but Orion is bright so I gave it a go. I had to take 2 sets of Ha data as my 240 sec frames had blown out the core. I used HDRComposition in Pixinsight to blend it with some 60 sec frames.
In a break from convention I applied Ha as a luminance layer to the RGB which has given it a slightly odd look - especially the running man which has lost it's usual shape. The red Ha figure is still there but it doesn't stand out as much. In the end I rather liked it - a bit of a twist on a familiar object.

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.
