Discover the RB Focus eXcalibur™, the revolutionary solution to automate your calibration shots and keep your optics impeccable! Say goodbye to cumbersome dust caps and welcome the era of hassle-free astrophotography.
 
Equipped with a powerful servo motor, a high-quality electroluminescent panel, and a 12-bit ADC, the RB Focus eXcalibur is the ultimate ally for performing Flats, DarkFlats, Darks, Bias, and other calibration shots remotely. Forget about those cold winter nights when you had to set up different devices – now everything is automated with a single tool!
 
Its robotic operation allows for automatic or on-demand calibration shots from any capture software compatible with the ASCOM Cover Calibrator standard, such as NiNa 2.x, Voyager, and SGP. Furthermore, we have improved the connectivity to cater to your needs. From the classic USB to wireless connectivity via Bluetooth and BLE for the mobile application, we offer different communication systems.
 
We understand that not all users prefer to use Windows or have alternative capture systems, which is why we have designed the RB Focus eXcalibur with multi-platform tools. Now you can control the equipment using our innovative RB Focus Virtual Pad app, soon available on iOS and Android. This one-of-a-kind app in the world of astrophotography allows you to save luminosity for different filters, control the panel, and much more – all from your mobile, tablet, or iPad!
 
Thanks to the high-resolution ADC, the panel offers a wide range of light intensities, allowing you to adjust the brightness with unparalleled precision to achieve perfect Flats with the right ADUs. Your images will appear completely flat and free of imperfections, even in the fastest systems on the market.
 
With the new dynamic brightness adjustment featured in the latest NiNa update, you can access a Flats capture mode that enables you to create a table with parameters for different filters and access them in the advanced sequencer. You can automatically program the equipment to perform all calibration shots at the end of the session and forget about it until the capture is complete!
 
Our obsession with design and simplicity led us to create a product with an incredibly easy assembly and disassembly process. You won't need complicated tools – in just 3 minutes, you can install the device on your OTA. And when it's time to remove it, simply open the panel, loosen a screw, and slide the module backward. The dovetail attachment system ensures secure mounting of the motor and panel on the tube.
 
Made with aluminum, carbon fiber, and engineering plastics, the RB Focus eXcalibur is resistant to wind gusts. Its dual-arm system ensures the necessary rigidity to withstand even the most challenging capture nights. It's the ideal solution for your field outings or leaving your telescope in a remote observatory!
 
Stop wasting time and effort on the calibration process. With the RB Focus eXcalibur, automation and quality come together in an unparalleled experience. Get ready to capture stunning images of the cosmos!
