Product Details

  • Focus fast, reliable, and accurate your telescope by using the Pegasus Astro FocusCube 2 Universal!

    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 2 has been developed to meet these requirements.

    Designed in high quality with modern electronics it can provide digital precise focus control from a PC.

    FocusCube 2 includes a stepper motor for absolute position focusing. Electronics and stepper motor are enclosed in a compact sized box.

    Do not be fooled by its size! This device can easily lift more than 6kg of imaging equipment when the telescope points to the zenith!

    This stepper motor is a high resolution geared stepper motor (Step Angle 7.5, Deg 120, Gear Ration 1:120). Its gearbox has very low backlash and high torque suitable to focus in micron-scale!

    You only need this device to get perfect focus! Attach the FocusCube 2 to your refractor/reflector/SCT telescope, plug the power and a USB cable, download ASCOM drivers or standalone software and you are ready to go!

    Love it

    This is my second FocusCube. I have one installed on my Sky-Watcher Esprit 100 and now on my Sky-Watcher Evolux 62. Installing on the Evolux 62 was easy and straightforward, but I did need to get some M4 x 25mm bolts from the hardware store. These work great with N.I.N.A for auto focusing during astrophotography sessions. OPT was top-notch as always in shipping this to me quickly.

    Pegasus FocusCube 2 Universal

    I am really enjoying using the focus cube on my 80mm refractor telescope. I am now able to control everything in my observatory remotely including focusing.

    Now it is easy to get pinpoint stars in all directions in the sky.

    Not Universal

    I placed a return request with OPT on Monday for this item. I have not heard back. Today is Thursday and they send me an email asking me to review the product? So, I will comply. It's not the fault of Pegasus, but this focus motor just doesn't fit on any of my telescopes. Other vendors and the Pegasus website tells you which telescope and focuser brands are compatible. I found this out after the fact. The OPT site just says it is "Universal". Well, it doesn't fit on the Sky Watcher ED100, or the Meade LX 85 6-inch reflector, and it does not fit on the Moonlite focuser for Schmidt Cassegrains. Anyhow, still waiting to hear back from OPT on whether they will accept the return without a bunch of restocking and shipping costs, as appears to be their policy.
