My big summer project and also the biggest project I ever tackled in my 2-year astrophotography career. This object was definitely one of the hardest in post-processing, Ou4 literally drove my crazy. After about 5 hours on the OIII Channel I saw a first hint of some data ;-)

All in all 54.8 hours of exposure time over a period of 3 months (18 nights) between July and September and countless hours of processing went into this image.

Many other images of this object only used Halpha and OIII filters to create a bi-color image. However, I decided to add another 14 hours in the SII channel to add a touch of gold/yellow along its rim.

I just hope that I didn't overprossed it, after so many weeks I just want to call it a day

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.
