I have fallen in love with this target and its simple beauty. It definitely requires more integration time to do it justice and so I think it will become my first multi-year project. Unfortunately, I no longer have astronomical darkness to capture the Oiii, so I intend to make sure that I start working on it as soon as it is possible next year. At 1.3 light years across, it is said to be one of the most perfectly spherical and largest spheres to be found in the night sky. I captured the RGB subs used for the stars during twilight and Oiii used for the Nebula during the short period of Astro darkness available to me. Once the RGB were combined and colour calibrated, it was possible to see the nebulosity in broadband, although very faintly. However, this was enough to see that the Nebula itself is actually a rich teal colour and not the vivid blue that this target is so often portrayed with. I did my best to retain that original teal colour in my image, although naturally it had to be a little lighter and brighter.

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.
