NGC2359 - Thor's Helmet

NGC2359 is a personal favourite of mine.
From the day I saw it for the first time, I had to go for it as soon as it was possible.

Being such a small target, I dusted off the Vixen R200SS 8" Newtonian and collimated it the best I could.
In the end, I still had non ideal stars in the corners, that's why I cropped them away. Working with the R200SS I realized that I'm a refractor guy through and through.
I won't continue with Newtonians for the time being, which is why I decided to process the limited data I gathered until now.

The final stack was still very noisy and did not allow to reveal the faint details without revealing noise artifacts.
I kept the stars very small in this process because of their aforementioned non-ideal shapes.

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.
