Thor's Helmet (NGC 2359)

Clear nights have been a rarity here over the past year, but in mid-January the clouds broke, clear weather was forecast, and I set to dusting off my gear ready for imaging. I decided to draw up a shortlist of possible targets and let my wife pick what we'd tackle next. She immediately gravitated to NGC 2359 (Thor's Helmet), loving the structure of it, and the cool colours that tend to arise from a HOO processing of the target.

By the time I set up my gear and remembered how to use it, I managed a couple of hours imaging on the first night. Then clouds rolled back in and it was another week before I could acquire a few more hours of data. My wife was excited to see the result, so I called it done there and processed it.

I initially processed the data with Siril and we were both happy with the result. However, I've started using PixInsight recently, and have seen noticeably sharper results from my colour camera data when performing a CFA drizzle (even at 1x). So, for my new Astrobin account, I decided to reprocess and see if this would help here too. It did. I saw an immediate improvement in contrast and detail.

Imaging was done with my larger Newt, using an ALP-T filter and a colour camera.

Overall, I'm happy with the detail I achieved on this one for such a short integration time. It's enough to convince me to hold out a bit longer before upgrading to a mono camera.

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.
