About
StellarMate is a powerful, compact observatory controller designed for amateur and professional astronomers who want to automate their astrophotography workflow without the complexity of managing multiple disconnected tools. At its core, StellarMate runs Ekos — a full-featured, cross-platform astrophotography suite — and is built on INDI (Instrument-Neutral Distributed Interface), the open astronomy instrumentation standard. Users can control mounts, CCDs, DSLRs, focusers, filter wheels, rotators, dew heaters, domes, weather stations, and more, all from one unified interface accessible via web browser, mobile app (Android/iOS), or desktop (Windows, macOS, Linux). The built-in smart scheduler enables true robotic observatory operation: select targets, slew the mount, start imaging, and let StellarMate handle the rest — including polar alignment, autoguiding, autofocus, and astrometry. Hardware offerings include the StellarMate X (a powerful, compact controller 4x faster than Raspberry Pi 4 with up to 128GB storage) and the StellarMate Pro (an anodized CNC case with 4x 12V outputs, dual dew heater channels, and variable stepper control). StellarMate OS can also be installed on existing Raspberry Pi 4 or Mini PC hardware, making it an affordable option for budget-conscious astronomers. Compatible with 15+ third-party clients including PixInsight, SkySafari, AstroImager, and SkyCharts, StellarMate fits seamlessly into existing astrophotography setups. It also features live stacking for Electronically Assisted Astronomy (EAA), an observational planner with millions of star and deep-sky object targets, and remote support capabilities.
Key Features
- Unified Equipment Control: Control mounts, cameras, focusers, filter wheels, domes, dew heaters, and weather stations all from a single interface without third-party plugins.
- Smart Robotic Scheduler: Automate entire imaging sessions with a powerful scheduler — select targets, slew the mount, and let StellarMate handle imaging, focusing, and guiding autonomously.
- Cross-Platform Access: Access and control your setup via Android/iOS mobile apps, Windows/macOS/Linux desktop, or any web browser for maximum flexibility in the field or remotely.
- Live Stacking (EAA): Perform real-time Electronically Assisted Astronomy (EAA) with live stacking, ideal for visual observers and public outreach sessions.
- Dedicated Hardware Options: Choose from StellarMate X (4x faster than Raspberry Pi 4, up to 128GB storage), StellarMate Pro (observatory-class with 12V outputs and dew heater control), or run StellarMate OS on your own Raspberry Pi 4 or Mini PC.
Use Cases
- Automating a backyard observatory for unattended overnight deep-sky imaging sessions
- Controlling a portable astrophotography rig in the field from a smartphone or tablet
- Running Electronically Assisted Astronomy (EAA) live-stacking sessions for visual observation or public outreach
- Scheduling and managing a remote or robotic telescope that operates without a physical operator present
- Integrating telescope control with post-processing tools like PixInsight for a seamless data acquisition and processing pipeline
Pros
- All-in-One Solution: Replaces a patchwork of tools by integrating planning, astrometry, autoguiding, autofocus, and image acquisition into a single ecosystem.
- Open-Source Foundation: Built on INDI and Ekos — well-established, community-supported open-source astronomy standards — ensuring broad equipment compatibility and ongoing development.
- Flexible Deployment: Works as a dedicated hardware appliance or as an OS image for existing Raspberry Pi 4 or Mini PC hardware, suiting a wide range of budgets.
- Wide Equipment Support: Compatible with a vast range of mounts, DSLRs, CCDs, focusers, filter wheels, and accessories, plus 15+ third-party astronomy clients.
Cons
- Steep Learning Curve: The breadth of features and astrophotography concepts (polar alignment, autoguiding, astrometry) can be overwhelming for complete beginners.
- Hardware Cost: Dedicated StellarMate X and Pro hardware units represent a meaningful upfront investment on top of existing telescope and camera equipment.
- Niche Use Case: Designed exclusively for astronomy and astrophotography, making it irrelevant outside this specialized hobby/professional domain.
Frequently Asked Questions
What is StellarMate and what does it do?
StellarMate is an IoT astrophotography controller that automates the control of observatory equipment — including mounts, cameras, focusers, and filter wheels — using the open-source INDI protocol and Ekos astrophotography suite. It enables robotic, hands-free imaging sessions.
Do I need to buy dedicated hardware, or can I use my own Raspberry Pi?
Both options are available. StellarMate offers dedicated hardware (StellarMate X and StellarMate Pro), but StellarMate OS can also be installed on a Raspberry Pi 4 or compatible Mini PC for a more affordable solution.
Which platforms and devices can I use to control StellarMate?
StellarMate can be controlled via Android and iOS mobile apps, Windows, macOS, and Linux desktop software, or any modern web browser. It also integrates with third-party tools like PixInsight, SkySafari, and AstroImager.
What equipment is compatible with StellarMate?
StellarMate supports a wide range of astronomy equipment including mounts, DSLRs, CCDs, focusers, filter wheels, rotators, dew heaters, domes, weather stations, and adaptive optics — covering most major manufacturers through the INDI protocol.
Can StellarMate automate an entire imaging session without manual intervention?
Yes. StellarMate's built-in smart scheduler supports fully robotic operation: it can automatically slew to targets, perform polar alignment, start autoguiding, run autofocus routines, capture images on a schedule, and handle meridian flips — all without user intervention.
