Active observatory monitoring

Good Night System

The only true solution to be able to sleep.

GNS monitors your unattended observatory session from your smartphone. When something goes wrong — a hang, power failure, guide failure, unexpected cloud — you're alerted immediately, wherever you are.

How it works

Two components, one mission

GNS pairs a lightweight PC program with a smartphone app that stays connected to your observatory session all night long.

PC software

A small, discreet program runs on your observatory PC. It tracks session progress — counting down timers, catching process hangs, detecting unexpected shutdowns — without needing to understand your automation software. It acts as a silent, always-on watchdog for everything running on the machine.

Smartphone app

The GNS app on your phone connects to the PC software and continuously monitors your session. You can see what's happening in real time — and the moment something goes wrong, your phone rings, vibrates and shows the alarm. Sleep soundly knowing you'll be woken if needed.

When it wakes you

Every failure mode, covered

GNS doesn't only wait for your software to tell it something went wrong. It catches the failures that automation software itself cannot see.

Session timeouts

If a task takes too long — slewing, calibrating, imaging, closing — GNS alerts you before equipment is left at risk.

Communication loss

Extended silence from your observatory PC — power cut, crash, network dropout — triggers an immediate alarm.

Watchdog monitoring

GNS monitors the entire PC for process failures. If your automation software hangs silently, GNS catches it system-wide.

Immediate alarms

Your automation software can trigger a GNS alarm directly — for guide failures, cloud detection, dome problems or any custom condition.

Session status

Not just alarms — GNS also gives you continuous status updates so you always know what the observatory is doing, not just when it fails.

LLLOD integration

Pair with LLLOD for a complete safety net: if LLLOD closes the observatory due to an unsafe condition, GNS confirms it happened and warns if it didn't.

Native integrations

Works with your automation software

GNS integrates directly with the most popular observatory automation platforms — no workarounds, no custom scripting needed.

A N.I.N.A. plugin is available for native GNS integration inside N.I.N.A. sequences. For other platforms, GNS can be triggered via the Windows PC software API.

Always know what's happening

The GNS app shows real-time session status, alert state and configuration — in a clear, readable format designed to be understood at a glance, even half-asleep.
