Description

North America Nebula capture from near Death Valley in the summer of 2023 (Bortle 1 region).

Exposure times:
30x180s (S)
30x180s (H)
30x180s (O)

I had a bit of difficulties with asi294mm camera banding, e.g.  noise that looks like horizontal stripes. I may try some day of these stripes disappear with more integration time, but for now my solution was to use SHO->RGB only to determine the chroma and use H (where the signal is the strongest) as luminance.
