## What is TRITON GOTO?

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.

• Select celestial objects directly from the sky chart
• Send your telescope to a target with one-tap GOTO control
• Plan visual observations and astrophotography compositions

Visual Alignment Tools: Make telescope setup simpler and more intuitive.

• Visual three-star alignment
• Visual polar alignment assistance
• Coordinate synchronization and position calibration
• Ideal for DIY equatorial mounts and custom GOTO systems

3D Telescope Model: See your telescope's current orientation in real time.

• Synchronize the 3D model with the telescope's status in real time
• View the telescope's pointing direction at a glance
• Monitor right ascension, declination, and changes in mechanical orientation
• Confirm system status while troubleshooting or observing

Complete Telescope Controls: TRITON GOTO provides comprehensive control of your OnStep system.

• Automatic GOTO slewing
• Manual movement and directional controls
• Tracking rate settings for sidereal, solar, and lunar motion
• Guiding rate adjustment
• Park and Home controls
• Meridian flip settings
• Limit and safety status monitoring

From completing your first telescope alignment to carrying out advanced astrophotography sessions, TRITON GOTO reduces time spent on complex equipment setup so you can spend more time exploring the universe.
