m42 (Orion nebula) Ha_superlum_RGB

m42 (Orion nebula) captured in LRGB with TS 80/544mm and in Halpha with Canon lens 200mm/f2.8. The post processing allows to show the resulting enhancement going from LRGB to Ha_superlum_RGB. The superlum layer is a blending of true layer and synthetic one for which I used also the HDR combination for better trapezium rendering. I used also a new accessory for this refractor setup which is a focuser.
The revision C includes stars acquired from the 80/480mm APO triplet with flat field corrector TSFlat2" to get better star shape. The trapezium is also better processed.

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.
