NGC7380 Wizard Nebula - First Light with FLI ML16200 - Image #2

This is the second processed image from my first light session with my new FLI ML16200.

NGC 7380 is commonly called the Wizard Nebula. It is located in Cepheus. Distance is on the order of 7,200 ly and is composed of an open cluster and predominantly Hydrogen region. The star forming region is about 100 ly across.

This region is devoid of background galaxies given its location in or near the Milky Way band. I have annotated brighter stars using the Tycho catalog but refrained from labeling even more from UCAC as the amount of annotation in this rich star field was overwhelming.

Overall I'm pleased with how this came out. As is usual, the OIII signal in particular was weak, and I could stand to at least double my integration time with this filter. Ironically it is supposed to be fairly bright in OIII, but that wasn't my experience. It was right around the full moon, and despite using 3nm wide NB filters I may have had interference particularly with OIII.

I actually did have more data in all channels acquired over several nights, but I was fighting thin cloud layers, so I was very selective with the frames and only kept about half of them. Another thing I've been applying with my NB processing lately are some PixelMath equations in PixInsight to neutralize the bright magenta star colors that result from the SHO color comination and green neutralization. This results in almost completely white stars with some interlaced in the brownish gas color. I have plans at some future date to include true RGB data of bright stars in these nebular regions to combine with the SHO images.

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.
