I extracted the starless Red channel from the L-eXtreme integration and combined with the RGB image from the UV-IR Blocking filter to enhance the reds while keeping the natural colors.

The RGB image is with the Astronomik L2 UV-IR Blocking Filter under Bortle 4 skies of Joshua Tree National Park. I arrived late at 10 PM, so I only kept 10 subs at 180 secs before the background became too bright due to the light pollution near the horizon.

The extracted red Ha channel is with the Optolong L-eXtreme Filter under Bortle 8 skies at home through multiple nights.

I attempted an HDR composite by imaging at 10, 30, and 180 seconds to retain the detail and color near the Orion Trapezium Cluster and pull out the faint nebulosity.

Total Time:
L-eXtreme – Montclair, CA
39 x 10 sec = 6 min 30 sec
40 x 30 sec = 20 min
97 x 180 sec = 4 hrs 51 min
Integration Time: 5 hrs 17 min 30 sec

UV-IR Blocking – Joshua Tree National Park, CA
20 x 10 sec = 3 min 20 sec
20 x 30 sec = 10 min
10 x 180 sec = 30 min
Integration Time: 43 min 20 sec

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.
