  • RB Focus eXcalibur Lite Motorized Flat Panel

    The RB Focus eXcalibur Lite automates your calibration workflow with a lightweight electroluminescent panel available in sizes from 80 mm to 355 mm. This system operates on standard 12V DC power via a 2.1 mm center-positive jack and weighs 145 g (the weight varies with the panel size ordered).

    Automated Calibration: An Electroluminescent Panel from 80mm to 355mm

    The eXcalibur Lite takes flat frames automatically or on demand with a robotic panel. Its electroluminescent panel is the light source for the flats that correct vignetting and dust shadows. It is built from carbon fiber, aluminum and engineering plastics, weighs 145 g (varying with the size ordered), and comes in sizes for dew shields or tube openings from 80 mm to 355 mm.

    Flexible Control: ASCOM, USB, and Bluetooth Connectivity

    The eXcalibur Lite follows the ASCOM Cover Calibrator standard, so any capture program that supports it can take flats automatically or on demand; examples are N.I.N.A. 2.0, Voyager and SGP. Connect it to a computer through its Micro USB port, or wirelessly through Bluetooth and BLE. RB Focus has also announced an RB Focus Virtual Pad mobile app for iOS and Android.

  • What software can I use to control the RB Focus eXcalibur Lite?

    Any capture program that supports the ASCOM Cover Calibrator standard. Examples include N.I.N.A. 2.0, Voyager and Sequence Generator Pro (SGP).

    How do I power the eXcalibur Lite at a remote imaging site?

    It runs on 12V DC through a 2.1 mm center-positive DC jack, so any 12V source with that output works, such as a 12V battery or an RB Focus power box.

    Can I control the eXcalibur Lite without a Windows PC?

    It supports Bluetooth and BLE as well as USB, and the device was designed with cross-platform tools in mind for users who do not use Windows. RB Focus has announced the RB Focus Virtual Pad mobile app for iOS and Android; check with us for its availability.

    How do I automate flats for my different filters with the eXcalibur Lite?

    In software like N.I.N.A. or SGP, you can configure your flat-frame sequence to automatically switch filters using your filter wheel. The software will then command the eXcalibur Lite to turn on, take the required number of exposures for each filter, and then turn off, all without manual intervention. You set the appropriate exposure time for each filter to achieve the target ADU (Analog-to-Digital Unit) value.

    What is the main advantage of the eXcalibur Lite panel?

    The primary advantage is its integration into automated imaging routines via the ASCOM Cover Calibrator standard. This, combined with its lightweight carbon fiber construction (~145 g) and flexible USB and Bluetooth connectivity, allows you to capture flat frames at the beginning or end of your session without being physically present at the telescope.
