This image of M78 is a stack of 22 x180 second subs taken from Iluka, Western Australia on 4 January 2022. The target was quite low, there was no moonlight and the air was humid and warm with variable seeing conditions. No filters were used: with the ASI294MC Pro paired with the SW 150 Apo cooling was set to -10'C. 180 second exposure results in significant light pollution contamination. I have since concluded that for my Bortle 6 area a better data set for processing is obtained for a given 2 hour imaging session using shorter exposures (60 seconds) allowing the collection of more images for stacking. There is no appreciable noise gain as a result of capture at -10'C verses +5'C.

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.
