Show HN: Nightwatch – a Mac menu-bar app that tells you when tonight is clear
Nightwatch is a new macOS menu-bar application designed to help amateur astronomers identify optimal times for stargazing and astrophotography. The app provides weather forecasts, target suggestions, and dark-sky location data.

Niche productivity and hobbyist software demonstrates the growing utility of localized data integration in desktop applications.
The full Moon, 26 September 2026, DWARF Mini, Richard Sutcliffe.
Silent macOS menu-bar app: tells you when tonight is clear enough for a long imaging session, and what to point at.
Taken with version 1.1 and a DWARF Mini, observing from two public dark-sky places: the North York Moors International Dark Sky Reserve (the popover, widgets and the week ahead) and the Malham National Park car park in the Yorkshire Dales Dark Sky Reserve (the rest of the Targets window).
Alerts: a heads-up an hour before sunset when tonight looks clear, with your plan and what the second forecast thinks, and a nudge as the clear window opens.
