I really like this nebula because I can see it with my naked eyes, from my light polluted backyard, even without my glasses. I have never seen it in a telescope yet. For this picture I needed to decide if I get the imaging rig ready or build up the visual scope because the clouds disappeared rather suddenly (forecast said 90% cloudy).

Since everyone needs an M42 picture in their gallery, I decided to go for it. Collimation of the RASA was not perfect yet, seeing (only 4 trapezium stars resolved) and transparency (60% images culled because of clouds) were mediocre and I think I might have overdone the HDR processing a bit. But comparing it with version B which is my first nebula picture from last year I feel I am making some progress with my imaging.

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.
