je viens de découvrir ce site . il vient faire concurrence a la ZWO Asiair . il a l'air complet , compatible avec pas mal de matos et open source . quelqu'un l'a t'il déjà essayé ?   https://www.stellarmate.com/     Description Overview StellarMate is the Next Generation Internet-of-Things Astrophotography gadget! The principle behind StellarMate is simple: Connect your equipment (Mount, DSLR/CCD, Focuser, Filter Wheel..etc) to StellarMate via USB/Bluetooth or Network. Connect to StellarMate from either your Mobile, Tablet, or Laptop/Desktop Computer. Start controlling your observatory and imaging from any major platform. A complete free astrophtography tool is shipped with StellarMate: Ekos. You can either use the built-in Ekos Astrophtogoraphy Tool, or download it on your Windows, MacOS, or Linux computers to remotely control StellarMate from any where! In addition to Ekos, StellarMate is compatible with many more applications, including PixInsight, PHD2, Sky Chart, and many more! From controlling a lone mount in the field, to orchestration of state of the art observatory, StellarMate is the solution you have been waiting for. Specifications StellarMate is based on Raspberry PI 3B+, a proven platform for embedded computers for many years. SoC: Broadcom BCM2837B0 CPU: 1.4 GHZ quad-core ARM Cortex A53 (ARMv8 Instruction Set) GPU: Broadcom VideoCore IV @ 400 MHz Memory: 1 GB LPDDR2-900 SDRAM Real Time Clock (DS3231) with battery. Storage: 16GB MicroSD card class 10. USB 2.0 ports: 4 Network: 300 MBPS Ethernet, 802.11b/g/n/ac Wireless LAN (2.4Ghz and 5Ghz), Bluetooth 4.0 HDMI: 1.8m Gold Plated HDMI cable. Power: 2.5A 5v power supply with convenient on/off switch. The power supply plug is US-type, however, a European-type adapter is also included. NEW RTC module: StellarMate now ships with a Real-Time Clock with battery to keep StellarMate time accurate even when power is off. A real time clock is critical for accurate astronomy & astrophotraphy work. Passwords The default StellarMate OS password is smate The default StellarMate WiFi HotSpot password is stellar@mate Learning StellarMate For new users, using StellarMate effectively can take a bit of a learning curve (like everything else) especially given the breadth of the features if provides.
