NGC2359 - Thor's Helmet

After record 2022 rainfall for much of Australia, it's been wonderful to have had mostly clear skies for the past 4 weeks. This has coincided with 3 weeks off work, providing a great opportunity to rediscover the nocturnal passions of astrophotography!

It's also allowed me to better explore the potential of my f/4 Quattro, which has remained largely unused over the past year. I had persistent challenges retaining collimation, but replacing the standard focuser with a Feather Touch assembly seems to have solved the problem. Imaging with a f/4 Newt has some extra challenges with collimation and dew, but the faster acquisition of narrowband is the bee's knees!

I've used this HOO attempt of Thor's Helmet as an opportunity to brush-up my PixInsight tools and techniques. Netflix has been replaced by a variety of YouTube channels, much to the chagrin of my very understanding wife.

Thanks for looking and CS.

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.
