M42 is one of those targets that everyone takes - and yet here I am almost 2yrs into this hobby and I hadn't taken a pic ;-)

This is 3 nights worth of data - and since its super-early in the season for Orion (all these pics were taken 1am-5am - which is pretty hard when you have to work the same day) I'm hoping to add some more time on this target, and post an update later this season.

I mucked around with different exposure lengths and then used HRDIntegration in Pixinsight. It was surprising how little difference there is between 10s and 60s on the Epsilon. Orion is so bright, everything washes out very quickly...and that core is sooo hard to process...

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.
