M42: Orion Nebula (42 Minute Express Version)

A two hour window of partly cloudy skies is not really enough time...but I was desperate to get out. It was enough to set up and get a little bit of data on the iconic M42. This was my first attempt with Orion, and I'd hoped for more integration time, but, alas, it was not to come to pass. Still, at 42min on M42 acceptable results are possible!

For a first effort on limited time I am quite happy. As always I paid closest attention to star color. I chose to process the data minimally, and so much of the extended surrounding nebulosity, while faintly visible here (as star-obscuring darkness), is not meaningfully rendered. I opted to maintain a higher overall image quality rather than showing detail that more integration time will bring out. I did take some artistic license with the color--just a little--because I could. I'm sure that with more data my tendency towards "realism" would keep me in check.

Description: Redux version (same 42min data) with excessively saturated color, for the variety of it, showing just how different processing workflows can affect outcomes.

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.
