Box one is the city. Blue Hour City is the reference dusk grade, sky deep blue against the first lit windows, with members for a single lit office window, evening traffic with the trails held against the blue, and the moment the lamps come on. Sodium Street pulls the vapour orange and accepts what that leaves: a near-mono frame graded honestly, with Cyan Guard to stop the cool pull swinging the pavement teal.
Box two is the deep sky. Night Sky is the wide-field baseline: black point deep, shadow tint cool, one variant per object from the Pleiades to an eclipse corona. Milky Way Core carries the dust lanes on texture, warm core against cool arms, global saturation held near neutral so noise is not lifted with it. Deep Sky finishes a stack: faint signal lifted, the emission bands separated, green treated as the noise it mostly is.
Box three is events. Star Trail keeps a long stack's sky gradient smooth, contrast carried by a curve rather than a slider, with dither added on purpose to break up the stepping. Meteor Watch holds the streak bright while the sky floor drops; it cannot recover a trail the sensor did not record, and the notes say so.
Box four is the moon, the daylit subject in a night set. Lunar Detail recovers the limb, raises crater texture along the terminator and pulls the disc to neutral. Below, a few presets from each box on the same frames.
