NGC1499 California Nebula . . . variations

A collection of image variations from my R, G, B and Ha data for NGC1499 combined with different techniques in PixInsight. I've processed these images between Christmas family fun and duties; narrowly avoiding incurring their wrath!

Rev A: Ha data only

Rev B: R_Ha_G_B with 50% of the Ha in the R channel

Rev C: Ha_R_G_B with 70% of the Ha in the R channel

RevD: adjusted saturation lowering pink tone to more red

Rev E: adjust saturation again

Rev F - completely reprocessed with new PI techniques; aiming for a natural look.

Rev G: revisiting old data.

I've decided in the end to retain the faint blue halos of the large stars; I had removed the halos in previous iterations but, whether it is because I've been staring at the screen too long, felt they looked more 'natural' with the halo (and PI doesn't have a very effective halo removal routine IMHO; it works to a degree).

Thanks for looking. Comments always welcome.

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.
