California Nebula (NGC 1499/Sh2-220) widefield

The California Nebula (also known as NGC 1499 or Sh2-220) is an emission nebula located in the constellation Perseus.
Its name stems from its striking resemblance to the outline of the US State of California when captured in long-exposure photographs.
This celestial wonder stretches across the sky for nearly 2.5 degrees, making it quite extensive. However, due to its very low surface brightness, it is extremely challenging to observe visually 1.
NGC 1499 was discovered in the 1880s by American astronomer Edward Emerson Barnard and it lies approximately 1,000 light-years away from Earth.

This image resulted from 49 hours of integration time using a f2 aperture, combining dual narrow-band and RGB data.
The framing was chosen to emphasize the dark nebula LDN1473 but it's not the most usual one.
In my opinion, the star 45 eps Per (the bright star on the right) adds balance and depth to the final composition.

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.
