The California nebula
This is stacked from multiple observations taken from SPA-1 in November 2021, I have reprocessed them to see if they produce better image than my first attempt. The California Nebula (NGC 1499/Sh2-220) is an emission nebula located in the constellation Perseus. Its name comes from its resemblance to the outline of the US State of California.
