Field notes
Nocturne organizes Seestar processing around reversible, inspectable steps rather than a single automatic conversion. The page says every step is cached, with before-and-after comparison and recipe saving for consistent folder processing. Its external-tool model is explicit: GraXpert handles background and gradient work, StarNet2 supports star separation, and ASTAP adds plate-solving when installed. The free fallbacks are presented as sufficient for operation, while RC-Astro is optional.
