Central Region of Orion

The sight of Orion in the southern sky around midnight signals the start of the winter astro-imaging season. I shot some widefield images of my old favorite the other night. The results reminded me both of how much I enjoy this region of the sky and how bad the light pollution is in my southern sky. The full image includes the entire Orion constellation, but I had to crop it down to the central region due to extreme LP near the horizon. I was happy to see a bit of Barnard's Loop visible along with the usual highlights including the Orion nebula, Flame nebula, and Horsehead nebula.

Imaged with 50mm Nikon at F/4, IDAS LPS D1 Clip Filter, and full spectrum modified Nikon D5300.

Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Stacked 41 subs (180 sec at ISO 200) for a total integration time of ~2 hours. Post-processed in Pixinsight: Cropped, gradient removal with ABE (multiple applications), MLT for noise reduction, Photometric Color Calibration, stretched using masked stretch, ACDNR for noise reduction, and Color Saturation boost.

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.
