Finally done with the California Nebula (NGC 1499) after a month of waiting for clear weather. I started acquiring Ha-data in late November but the weather turned for the worse in CT so it wasn't until mid-December that I was able to collect some color using my UHC-clip.

Like our own sun the California Nebula is drifting through the Orion Arm of the Milky Way Galaxy. By chance it happens to resemble California on the west coast of the United States. It is about 1,500 ly from Earth in Perseus and approximately 100 ly long (source: APOD). For reference, the closet star to our sun, Proxima Centauri, is 4.2 ly away. As any chemistry student knows, the red color is caused by excited electrons from ionized hydrogen falling from the 3rd energy level to the 2nd energy level - that transition releases red photons...

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.
