Explore Scientific iEXOS Equatorial Mount and Tripod with GOTO PMC-8 System

Explore Scientific designed their IEXOS-100 PMC-Eight Equatorial Go-To Tracker System Mount to provide users with a platform built for precision, and to support small-to-medium sized optical tubes, astrophotography, and imaging rigs.

Although it is internally complex, the GOTO system can easily be operated from your own Apple, Android, or Windows tablet using the ExploreStars app. The app is intuitive and easy to use and features a database of over 70,000 objects with an intuitive user interface controlled with the device's touchscreen. Multiple alignment procedures, slew and tracking rates, and customized guided tours allow it to be easily set up and get users observing quickly with minimal frustration.

One of the standout features of the iEXOS-100 system is its German equatorial design. When it comes to tracking the stars with a telescope, there is nothing that compares to a German Equatorial Mount (GEM) because it will precisely follow objects as they rise in the east and set in the west.

For observers, a GEM makes it easy to keep your celestial target in your eyepiece. For imagers, it helps you avoid common astrophotography pitfalls like field rotation.
