Thor's Helmet (NGC 2359)

This was captured under difficult weather conditions. First of all, it's been rainy for weeks here. When it wasn't, it was full moon or foggy. When yesterday I finally saw some stars in the night, I took advantage of this to try to capture a target I wanted to have for years but didn't get the opportunity to do: Thor's Helmet.

It was difficult because the sky wasn't transparent, and there were quite a lot of clouds. Therefore, almost every raw frame has clouds somewhere. However the magic of software processing makes it so that it's possible to get some nice data out of it. Obviously I would have liked to capture more data too, but it was already too late: when I started capturing, the target was roughly 17° high, which isn't great (and I had to wait for it to pass over the trees). Then it topped at 30°, but when it did, clouds were all over so I had to stop the session. This explains why the image is quite noisy.

I doubt I will have an occasion to capture more data this year, so be it!

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.
