Orion Nebula and Running Man Nebula

This is a study in processing methods on medium-quality data: all images were acquired unguided on a ZenithStar 61ii, Nikon D5600, and Optolong L-pro mounted on a Star Adventurer, using the D5600's built-in interval timer.

The first version used Sequator to process a bit over 480 x 30" taken with a L-pro on a Nikon D5600.

The second version is reprocessed with AstroPixelProcessor on 467 x 30", with a lot of attention paid to nonlinear light gradients. APP was challenging on this one, as it did weird things with my stacks and initially made the Orion Nebula very pink, but I managed to get some good results after further adjustments in photoshop.

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.
