AstroLink 4 Bee on 80mm refractor

AstroLink 4 Bee

AstroLink 4 Bee is a standalone astrophotography setup controller based on a T4 Pro or T5 mini PC with Windows Pro operating system. It covers similar functionalities to AstroLink 4 Pi, but the operating system is Windows, so all the astronomy software like N.I.N.A., MaxIm DL, Sequence Generator Pro, PHD2, ASTAP, ASI Studio and many others is ready to pick up. Both the ASCOM driver and dedicated control panel are available to control all the functions of AstroLink 4 Bee.
Check AstroLink 4 Pi if you are looking for the device controlled by Raspberry Pi module.


AstroLink 4 Bee is powered with 12V via a reliable XT60 socket. It can connect to an existing WiFi and once connected, an imaging session can be planned via a remote desktop or dedicated application. Any computer, laptop, or tablet can be used to plan and control the imaging session.
