M42 Widefield

A very fun night since it was the first one in 4 months for me to get out and enjoy the night. I wasn't quite sure how best to approach this shot, so I collected 7x480s, 22x300s, 10x30s, and 10x10s worth of data and ended up throwing out all the 300s worth of data since I got more background with the 480s stack. If I had to do it again, I would have not done the 300s subs and just did 480, 30, and 10s as that would have minimized the noise on the background. Lucky for me there is a lot of signal to begin with in this region. The data is processed in Pixinsight and I did 3 "layers" of HDR in Photoshop by hand. This year, I even managed to focus the image (last year, for some reason, focus did not seem to be one of the things I "focused" on). The night was -19C outside and the focus knob hurt to touch, which is part of the fun.

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.
