Strategies for optimal sky subtraction in the low surface brightness regime
The low surface brightness (LSB) regime (μ g ≳ 26 mag arcsec -2) comprises a vast, mostly unexplored discovery space, from dwarf galaxies to the diffuse interstellar medium. Accessing this regime requires precisely removing instrumental signatures and light contamination, including, most critically, night sky emission. This is not trivial, as faint
