NGC 1499 - California Nebula in HOO Palette (EasyQuest)

NGC 1499 - California Nebula in HOO Palette

Comments
For this work-in-progress project. I decided to go ahead and process an HOO palette of NGC 1499 - California Nebula in the constellation Perseus as I collect more SII for SHO final project. OIII is the hardest part to pull out as it is really faint. A single sub of OIII looks almost like a star field. I really had to push the OIII data in this to make it as bright as the HA. The final image turn out very well as it shows the OII and HA very well. Enjoy~

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.
