It turns a repetitive task like capturing flats into a precise, automatic process that fits naturally into your astrophotography workflow, and it is designed to work equally well on portable rigs, permanent installations and remote observatories.\u003c\/p\u003e\n\u003ch2\u003eCompact, lightweight motor unit\u003c\/h2\u003e\n\u003cp\u003eAt the heart of the system is a compact and lightweight motor unit, designed to adapt more easily to telescopes of different sizes, including smaller instruments where space and weight matter most. A powerful servomotor keeps movements reliable and repeatable during every session, and the two-arm design provides the rigidity needed to hold the illumination panel steadily.\u003c\/p\u003e\n\u003ch2\u003eNeon LED panel with 4096 brightness levels\u003c\/h2\u003e\n\u003cp\u003eThe eXcalibur 4.0™ pairs its servomotor with a neon LED panel calibrated to the spectrum of sunlight, providing natural, even illumination for your flat frames. A high-resolution 12-bit system offers 4096 individual brightness levels, so you can match the panel's intensity precisely to different cameras, filters, exposure times and optical configurations. That makes it easier to reach the ADU level you want and to create consistent flats even with fast optical systems.\u003c\/p\u003e\n\u003cp\u003eAn integrated heater helps prevent dew from forming and keeps the panel operational during long sessions in demanding conditions.\u003c\/p\u003e\n\u003ch2\u003eWireless control with Wi-Fi and ASCOM Alpaca\u003c\/h2\u003e\n\u003cp\u003eBuilt-in Wi-Fi and ASCOM Alpaca compatibility let you control the device wirelessly and reduce the number of cables around your telescope. Through ASCOM Alpaca, the eXcalibur 4.0™ communicates with compatible applications over your network and integrates with software such as N.I.N.A. without needing a physical USB connection between the eXcalibur and your capture computer.\u003c\/p\u003e\n\u003cp\u003eYou can also control it from its integrated web interface. From a computer, tablet or iPad, simply open a browser to open or close the panel, change the illumination level and manage its main functions, with no dedicated control app to install.\u003c\/p\u003e\n\u003ch2\u003eAutomated flats with N.I.N.A.\u003c\/h2\u003e\n\u003cp\u003eIntegration with N.I.N.A. takes automation further. With dynamic brightness adjustment, you can set specific parameters for each filter and add them directly to the Advanced Sequencer, so the eXcalibur 4.0™ runs your calibration frames automatically as part of your own capture sequence. You can finish your session, close the system, take your flats and complete the calibration process with minimal intervention.\u003c\/p\u003e\n\u003ch2\u003eSimplified mounting and durable construction\u003c\/h2\u003e\n\u003cp\u003eThe mounting system has been redesigned and simplified to reduce installation complexity and make the device easier to fit and remove. The eXcalibur 4.0™ is built from aluminum and engineering plastics, combining light weight with the strength to stay stable in operation.\u003c\/p\u003e\n\u003ch3\u003eTechnical
