TRITON GOTO - OnStep Control
Control your OnStep Telescope
Free · Designed for iPad. Not verified for macOS.
Control your telescope easily with TRITON GOTO. Enjoy star charts, precise GOTO control, and smart observation tools.
TRITON GOTO makes controlling an OnStep telescope easier. One app brings together the control features you use most in everyday operation.
Designed specifically for OnStep and OnStepX systems, TRITON GOTO is a comprehensive telescope control app that combines telescope operation, an interactive sky chart, alignment tools, and real-time 3D visualization to support your observing and astrophotography workflows.
Whether you are an astronomy enthusiast beginning to explore the night sky or an advanced user building a DIY equatorial mount, TRITON GOTO helps you set up and operate your telescope more easily and efficiently.
Interactive Sky Chart and GOTO: Explore the night sky with the built-in sky chart engine.
