NGC 1499 - California (SII - Ha - OIII)

NGC 1499 using SHO color palette, a mustard version. The final version I prefer is HSO, Version C.

The color channels are:

Red channel : (60% S-II + 40% Ha)

Green channel: (30% S-II + 30% Ha + 40% O-III)

Blue channel: (100% O-III)

Version C color channels are:

Red channel: Ha

Green channel: S-II

Blue channel: O-III

This project is now completed. I must say, it is much easier to process monochrome data than one shot color data. This image has had minimum processing, the simpler the better for me.

Looking back, perhaps, I should have shifted the color channels, by 3 to 5 pixels as the edges of some stars are not perfect. Next time, I will.

I am not a fan of the 'mustard' color, however, my goal was to produce SHO images.

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.
