PegasusAstro FocusCube 3 – automatically sharp
Anyone imaging with a camera knows the problem: even small temperature changes during the night shift focus, and focusing by hand is tedious and imprecise. The FocusCube 3 takes over this task. It mounts on your telescope's existing focuser and focuses quickly and repeatably under computer control – fully automatically too, via autofocus in programs such as N.I.N.A., SGPro, Voyager, APT or MaxIm DL.
With the supplied digital temperature sensor, your imaging software can adjust focus automatically as the telescope cools during the night.
Universal mounting
The motor attaches to the focuser with a universal L bracket with slots and rails, and connects to the focus shaft via a coupler. Five couplers with 4 to 8 mm bores and screws in various sizes are included. According to the manufacturer, the FocusCube 3 has been successfully fitted to, among others:
- Baader Steeltrack and Diamond Steeltrack
- Askar, Explore Scientific, MoonLite, StarField Optics, Stellarvue
- Sky-Watcher Esprit
- Starlight Instruments Feathertouch
- Takahashi FS-60, FSQ, TOA, TSA-120 and Epsilon
- Vixen ED81S
- William Optics GT71 and RedCat
Powerful and precise
A high-resolution geared stepper motor (120:1 reduction) provides fine steps and high torque. This lets the FocusCube 3 reliably move heavy imaging trains of up to 6 kg – even when the telescope points straight up and the motor has to lift the full load. The low backlash ensures clean focus curves during autofocus.
Connect via USB or Wi-Fi
- USB-C: a single cable for power and data – no extra power supply needed
- Wi-Fi: its own hotspot or connection to your home network (2.4 GHz); USB and Wi-Fi can be used simultaneously
- Browser control: via focuscube3.local – no driver installation, on any operating system
- ASCOM Alpaca built in, plus INDI and INDIGO
- PegasusAstro Unity: full control and profiles for different telescopes
- Hand control: port for the optional EZY Focus hand controller – handy for visual observing
Good to know
- The FocusCube 3 fits a great many, but not all focusers. The list above shows successfully tested models. Feel free to ask us whether it will fit your telescope.
- Installation usually involves removing the focus knob on one side of the focuser and fitting the motor to the shaft with the coupler. Some practical skill is helpful.
- Power is supplied via USB (5 V) only. The USB port on your computer or hub must supply enough current (up to 900 mA). The supplied cable is 0.5 m long – ideal with a USB hub at the telescope, e.g. a PegasusAstro Pocket Powerbox.
- Wi-Fi in the 2.4 GHz band only.
- The EZY Focus hand controller is not included.
