Celestron Professional StarSense Explorer DX 102AZ 102MM F/6.5 AZ Refractor With Smartphone Adapter Astronomical Telescope#22460

• 1. Download StarSense Explorer app from the Google Play (Android) store or App Store (iPhone)
• 2. Place an Android smartphone or iPhone in the included StarSense Explorer dock attached to, and aligned with, the optical tube 2-minute procedure to align the phone with the telescope App generates a list of celestial objects currently visible
• 3. Select the object to view and arrows to appear onscreen, guiding the user as they move the telescope
• 4. When the object is ready to view, the bullseye turns green
• 5. 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 is 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

• 102mm f/6.5 aperture to view the moon, planets, constellations, and bright deep-sky objects like clusters and galaxies
• 650mm focal length produces a moderate magnification potential with a highly portable length and weight
• Refractor design requires very little maintenance by the user or collimation over time
• Anti-reflection fully coated glass optics maximize light transmission through the light path to ensure bright and clear views with improved resolution
• Resolution: 1.37 arcsec, Rayleigh; 1.14 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

Included Accessories

• 90° erect-image diagonal corrects view to use the telescope as a conventional spotting scope while providing a comfortable viewing angle, especially when the scope is aimed overhead
• 25mm eyepiece produces a low 26x power for observing the moon, planets, deep-sky objects, and constellations
• 10mm high-magnification eyepiece yields 66x power for detailed views of the lunar surface and planetary features
• An unmagnified StarPointer finderscope places a simple red dot in the field of view to make alignment and star hopping navigation faster and easier
