We design and build astro instruments that keep your observatory running safely on its own—cloud detectors, roof controllers, sky quality monitoring and more. Made by people who observe and image.
✦ Made in the Milky Way
A fully automated observatory is built in layers. Each layer adds capability and safety, you can start with just monitoring and expand from there. These are the building blocks.
Weather & Sky Monitoring
Know when it’s safe to open and when to close. Clouds, rain, humidity, wind, and more, measured continuously and acted on automatically.
Observatory Control
Open and close your roof or dome automatically based on conditions. Control equipment, motors, switches and sensors from a single controller.
Alerts & Emergency Protection
Stay informed when something needs attention, and make sure the observatory closes itself if no one responds. Two complementary systems.
Dew Control & Other Products
Keep your optics clear through the night and mount multiple telescopes on a single setup. Smaller range, but useful additions to any observatory.
Our Automate Your Observatory guide walks through every layer, from basic sky monitoring to fully hands-off operation. Read it before buying anything.
A few highlights. CloudWatcher and Dragonfly are what most customers start with, and keep for years.
Provides reliable readings for cloudiness, rain, sky quality, temperature, and optionally humidity, pressure, and wind. The device most customers start with and keep for many years.
Learn more → Observatory Control · Since 2016 DragonflyControls roll-off roofs and other motorised enclosures. Works standalone or integrated with the CloudWatcher for fully automated operation. Proven over many years in the field.
Learn more → New · 2026 Sky Quality Meter LanternfishA highly configurable, portable, Wi-Fi sky quality monitor for measuring MPSAS and accessing the data from other devices. The latest addition to the range.

Learn more → Shared Observatory Control StarlingRoll-off roof controller for shared observatories. Multiple users, one roof. With independent interfaces, coordinated access control, and safety measures.
Learn more → Portable Cloud Detector PocketCW2Features readings for cloudiness, sky quality, temperature, humidity, pressure, and also wind detection. Compact and Wi-Fi enabled for portable setups, includes a free app for monitoring from different devices.
Learn more →Lunaticoastro started as Lunático Astronomía in Torrelodones, Madrid in 2006. It was founded by Jaime Alemany, an astrophotographer who wanted tools that actually worked. Everything we build tries to make it possible to keep a remote observatory running safely through the night so the imager doesn’t have to be there. In 2025, we opened Lunaticoastro Pacific Ltd in Hamilton, New Zealand, to serve customers in the Asia-Pacific region.
We don’t build products with planned obsolescence. If something can be repaired, we want it repaired.
We say what our products do and what they don’t. Specs are honest, claims are verifiable.
You get answers from people who know the product. Good customer support can't be replaced!
