California Nebula (NGC1499) SHO

The California Nebula (NGC 1499/Sh2-220) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It lies at a distance of about 1,000 light years from Earth. Its fluorescence is due to excitation of the Hβ line in the nebula by the nearby prodigiously energetic O7 star, Xi Persei (also known as Menkib, top right). The California Nebula was discovered by E. E. Barnard in 1884 (Wikipedia).
This is a Hubble Pallete image, a false color combination of Sulfur, Hydrogen and Oxygen made famous by the Hubble Space Telescope.
Exposure: 28 hrs of exposures (10 hrs Ha, 8 hrs Oiii, and 9hrs Sii) from my Bortle 4/5 backyard
Telescope: Skywatcher Esprit 100 ED APO
Imaging Camera: ZWO ASI 2600MM Pro
Guiding: Skywatcher EVOGuide Scope with ZWO ASI120MM camera
Filter: Optolong SHO Filters with ZWO 7x36mm EFW
Mount: Skywatcher EQ6R-Pro
Calibration: Flats and flat darks
Hardware Control: ASIAIR Pro, Pegasus Power Box and ZWO EAF
Processing: The selected images were pre-processed and processed using Pixinsight.
As always constructive criticism is welcome and appreciated. I am always looking for ways to improve my image capture and processing skills. Thanks for looking.

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.
