Another first light for Orion Great nebula in O-III

VERSION C is the actual field of view, uncroped, as seen @ f7.9 (152/1200mm) with the 24 mo/pix full frame sensor of the D750. Size of pixels : 5.9micron. No flattener either. Field depth : 15.30

Tonight, I prepared my first ever session under the sky, in the cold evening with the full set-up... and a first experience with O-III filters, mixed with regular "lights".

This image contains almost all that can go wrong, from the bug on the lens (3 images spoiled as you can clearly see) - or was it an Alien !? Than my camera started to blow half of my frames (complete psychedelic effect, I should post one for you to understand.

My 3 star's align was wronged by a very biased North align... Oh well, I'm so happy with this mess!

VERSION B / field depth : 15.90 (deepest so far)

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.
