The Great Orion Nebula

I was waiting for some clear moonless night to get some data on this target. I was lucky on 17Nov, a night with great transparency, just before heavy clouds and rain started :-) This is just a bit more than 3 hours total exposure. I will add more if the skies allow. A classic target with a high dynamic range, it seems that 150sec exposure with my colour camera allowed me to shoot the core without over saturating it. HDRMultiScaleTransform tool in Pixinsight took care of the core :-)

22/11/2020: Additional 3 hours data - reprocessed. Less aggressive core processing and background structures-dust clouds enhancement.

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.
