All I Saw Was Purple: Crescent Nebula

Went back into the way back machine in my archives and pulled this data set back out. It is a very light integration taken in my backyard with a Sony CCD camera, so it's defintely noisy, but modern tooling did do a fair job of cleaning it up. The palette in use here was generated in the NB Color Mapper, and I did not do anything out of the ordinary, as HA is mapped to Red and OIII is mapped to blue. It came out with this fairly interesting purple-like hue that I thought was pretty neat, considering if you take red and blue -- the outcome should be purple.

The strength of the signal here is fairly good, in fact better than I recall it. I may have to add this to the CDK14 system next summer and collect a good amount of cleaner data.

The soap bubble pops out rather easily in this rendition. You do not really need to go hunting for it. The blue on the Crescent shell is very visible, and again I did not really do anything special to make that happen as it was like that in the preview of NB Color Mapper.

The title is a reference to a statement made by a USC quarterback years ago, after a game against my UW Huskies, in case anyone wonders.

Hope you enjoy the image. Feel free to comment as well.

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.
