NGC 2359 - The Duck Nebula (Thors Helmet)

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

NGC 2359 (Thor’s Helmet, aka Duck Nebula) in the constellation of Canis Major - this time with a little extra data collected and the image rotated 180 degrees to the more common view. Total exposure is now 100 mins for each of the S, Ha and O filters (5 hours exposure via 5 minute subs). The Sulphur filter didn't really add much signal, I should have spent the 100 mins on Sulphur looking for a deeper signal on Ha and O. Nevertheless a few reds are creeping into the image. Colours are mapped as SHO = RGB. Skywatcher 8 inch f5 Newtonian, NEQPro6, ASI1600mm Pro (-10C), unity gain, ZWO 7nm NBand filters, guiding with ASI224mc and PHD2.

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.
