Astroasis Rose Electronic Focuser

Oasis Focuser Rose — In a League of its Own

The Oasis Rose is a premium electronic focuser engineered for astronomers who demand precision, reliability, and complete control — even in the toughest conditions. With sub-micron accuracy down to 0.1μm per step, a powerful 5kg+ load capacity, and a twistable manual clutch, Rose brings intelligent automation to your night sky sessions while giving you full manual access whenever you want it.

Designed for all seasons and scopes, it features an integrated heating module to prevent failure in cold climates, and a compact, lightweight body that makes installation easy for practically any telescope. The onboard stall detection protects your gear, while dual temperature sensors and smart thermal regulation keep performance stable under all conditions.

But what truly sets Rose apart is its manual clutch mechanism — one of the most unique and versatile features in its class. With a simple twist, you can instantly disengage the motor and take full manual control of your focuser, no hand controller needed. Unlike most other focusers on the market, it offers manual and electronic control without the need for a computer or hand controller thanks to its Bluetooth connectivity, dedicated iOS/Android app, and twistable clutch mechanism.

Key Features

• Clutch Mechanism: Instantly disengage the motor with a simple twist for complete manual control, no hand controller required.

• Bluetooth Wireless Control: Control your focuser wirelessly via our intuitive mobile app for iOS and Android — without a PC.

• Automatic Stall Detection: Safeguards your focuser and gears by reliably detecting stalls and stopping motion promptly.

• USB-C & 12V DC Dual Power Options: Most setups require only USB-C for power. Only the heaviest image trains will require the optional 12v power input.

• USB HID “Driverless” Integration: Say goodbye to the headaches of legacy COM port setups. Compatible out of the box with ASCOM, INDI, Indigo, Linux, Windows, macOS, and Raspberry Pi.

• Built-In Heating Module: Prevents the focuser from seizing in cold weather for dependable performance.

• Environmental Sensor: High quality DS18B20 temperature sensor included.

• Micron-Level Precision: Achieve focusing steps as small as 0.1μm for pinpoint sharpness. Step size is typically ~0.8μm

• Heavy Load Capacity: Drives loads over 5kg effortlessly, perfect for demanding astrophotography rigs. We successfully lifted 8kg at zenith using 12V power.

• No Additional Backlash: Precision machining ensures that no backlash is added to any system. Backlash-free focusers like Crayfords and Feathertouch will remain backlash-free.

• Universal Clamp System & Quick-Release Clutch: Simplifies installation and allows fast switching between manual and electronic control.

• Integrated Electronics: Combines motor, controller, and electronics into one compact, lightweight unit for easy setup and minimal clutter.

• Billet Clutch Lock: Prevent unintended actuation of the clutch with built-in clutch locking mechanism

  

Seamless Compatibility and Connectivity

Supports ASCOM, INDI, and INDIGO, with a modern USB HID interface providing native support on Windows, macOS, or Linux, eliminating conflicts caused by virtual COM ports for smoother, more stable imaging setups. Instantly connect the first time, every time. No conflicts, no manual COM port selections, no failures, and no complicated connections—just seamless, reliable connectivity. 

Proven Precision & Reliability

Tested over multiple autofocus runs with NINA, the Oasis Rose consistently maintained focus within less than 8μm variation, boasting R² values above 0.99 on every curve. This focuser is built for accuracy, repeatability, and absolute trust in your imaging workflow.

Here are twelve consecutive autofocus runs. Please note the consistency of the focuser position after each run, speaking to its extreme precision and repeatability.

Universal Telescope Compatibility

Rose offers a wide range of clamps, brackets, and adapter kits to ensure compatibility with practically any focuser. If purchasing your first Astroasis Rose, select the appropriate adapter kit at checkout.

To simplify your purchase, we’ve bundled Rose with its relevant adapter kits under a single SKU, but you also have the option to buy the Rose Basic Suite and adapter kits separately. Please note that the Rose Basic Suite requires the appropriate adapter kit to attach to your telescope. If you’re simply moving Rose to a new telescope, you can just buy the appropriate adapter kit and migrate it over in minutes.

If by chance your telescope requires a custom solution, we’re happy to design a bracket tailored just for you.

What’s in the Box?

In addition to your adapter kit, the following items are universal and included in every basic suite. As a reminder, you must purchase the appropriate adapter kit to install Rose electronic focuser.
