M42 - Orion Nebula from the clear skies of Corsica

Made in one night after shooting the Pleiades, under the clear skies - Bortle 3 - of Corsica in France.

It is shoot with a portable setup made of a Sigma 105mm macro f/2.8 on an iOptron Skyguider Pro, guided with a small guidescope zwo 30/4 and asi120mm Mini.

Shoot in LRGB (Astronomik filters) : my second target ever with a monochrome camera and colors filters.

Description: New version based on the same data. I have used the last version of Siril, that allows for a 32 bit worflow and output, better for further treatment of HDR images.
I have worked on the high contrast regions, to make the nice structures of M42 more apparent. But lot of noise is coming doing so in dark areas... hard process. Should have imaged more hours :-)

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.
