StarSense System

• Download StarSense Explorer app from the Google Play (Android) store or App Store (iPhone)
• Place an Android smartphone or iPhone in the included StarSense Explorer dock
• 2-minute procedure to align the phone with the telescope
• App generates a list of celestial objects currently visible
• Select the object to view and arrows appear onscreen, guiding the user as they move the telescope
• When the object is ready to view, the bullseye turns green
• The StarSense app utilizes a "Lost in Space Algorithm" (LISA) to accurately calculate the current location and orientation by using the phone's GPS data, gyroscopic input, and camera to map the night sky and compare it to the app's database to accurately align and orient the scope and determine what is visible overhead
• App is self-contained; no cell signal required for use far off the grid

Compatible Smartphones:

• Android 7.1.2 and higher manufactured in 2016 and later, with camera, gyro, and accelerometer
• iPhone 6 and newer

Optical Tube Assembly

• Massive 130mm f/5 primary mirror enables users to view the moon, planets, stars, globular clusters, and other deep-space objects like galaxies, while reducing the secondary mirror obstruction, thus improving resolution
• 650mm focal length produces a moderate magnification potential with a highly portable length and weight
• Newtonian reflector optical design provides a large clear aperture without the restrictions on size experienced by refractor designs
• Highly reflective aluminum-coated mirrors improve light transmission, color rendition, and contrast
• Secondary mirror obstruction: 45mm (1.73"); 34% by diameter, 11% by area
• Resolution: 1.07 arcsec, Rayleigh; 0.89 arcsec, Dawes
• Reliable single-speed rack-and-pinion focuser
• Standard 1.25" holder accepts the most common size eyepieces and accessories, including the two eyepieces in this kit

Mount and Tripod

• Manual alt-azimuth mount design is simple to set up and move
• Single fork-arm design reduces weight without sacrificing stability
• Dual axis slow-motion control cables provide an easy way to move and precisely track objects with reduced vibration
• Simple setup and breakdown with dovetail saddle
• Adjustable-height aluminum tripod accommodates a variety of users and observing positions
• Maximum height of 49" (124cm) including mount
• Center tray holds accessories such as eyepieces and filters
