SH2-254 "The Other Orion Nebula" from Data taken on 3/2022 and 2/2023

SH2-254, 255, 256 and 257 "The Other Orion Nebula" are a group of nebulae
8000 light-years distance in Orion.

On 3/12/2022. The Moon was about 70% illuminated and
only about 20 degrees from my target. It was the coldest, windy night this year.
I had to throw out about 15% of the subs I took because of wind vibration.
So, I was pleased with the result and still have all my fingers and toes.

On 3/04/23 Again a bit windy with the Moon close to the target so I
limited exposures again to 180 seconds. On 3/7 the Moon was further from
target so I increase exposures to 300 seconds. I think the data I took could have been
better and even with over 10 hours total integration time my final image was not much of
an improvement from last years 3+ hour image.

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.
