A must have for successful astrophotography sessions

Focus fast, reliable, and accurate your telescope by using the “FocusCube 2“. The evolution of technology in astronomy requires a system that will assist the focusing of the telescope with great accuracy.

Fast optics and modern camera devices require automatic focusing in every small period of time as the temperature can affect the focal length and modify the optimal focus position. Pegasus FocusCube has been developed to meet all of these requirements.

FocusCube has a very low backlash and high torque suitable to focus in micron scale.

Due to its high resolution and torque, the FocusCube should be placed on the coarse knob / direct shaft of your telescope focuser

High resolution
Geared Stepper Motor
in an aluminum enclosure

Designed in a high-quality CNC body with modern electronics, FocusCube provides digital precise focus control, for absolute position focusing.

Solid motor couplers in package

motor couplers

Five solid, different bore size, motor couplers are provided so you can select the coupler that fits to your focuser’s shaft. Choose between 4mm to 8mm couplers

Universal Bracket

We have designed the L-shaped bracket to easily fit onto most focusers in the market. The lower part of the redesigned bracket can be replaced with a slimmer rail (included) for better compatibility with Newtonian and other low-profile focusers. This L-shaped black anodized aluminum bracket is hard to bend, has cut rails, and can be attached to a wide range of focusers.

Accurate and repeatable focus v-curves

FocusCube v2 is fully compatible with all modern imaging suites, NINA, SGPro, Voyager, APT. MaximDL etc.

Autofocus by using a v-curve model is a piece of cake operation

V-Curve Results are accurate and repeatable each time the autofocus routine is triggered

Additional Information

Temperature Probe

An external digital temperature sensor input is located on the side of the focuser. A digital temperature sensor is included in the package. The probe can be placed near the focuser so the exact temperature of the focuser / environment can be seen through the supplied software or ASCOM driver.

Expansion Port / Manual Focus

FocusCube includes an expansion RJ45 port at the back of the enclosure. This port provides input for the temperature sensor. An optional hand controller for manual focus control can be acquired for those who might want to add this functionality.. This is an Optional Accessory

ASCOM and INDI support

FocusCube v2 supports latest ASCOM and INDI framework.

Firmware upgrade support

Firmware supports re-programming via the USB 2.0 connection using upgrade software ((only available for Windows), for future upgrades which may become available. We constantly receive feedback from our customers and keep updating the firmware and software with new features.

Dimensions & Weight

56 x 63 x 39 mm / Weight 280g

Unity Platform support

Full control of the FocusCube device can be achieved through Unity Platform.

Different profile names can be used to identify each setup

Software

Pegasus Astro Unity Platform is our new all around application. Our goal is to provide a robust and modern application that is going to support current and future products under one roof.

A modern frontend allows the full control of all Pegasus Astro devices.
Moreover, a REST JSON api helps developers from 3rd party software to interact with our products.
As we continuously develop our applications, based on customer feedback, lots of innovative features are going to be added in upcoming releases.
