Explore Scientific iEXOS-100 PMC-Eight GoTo WiFi and Bluetooth Tracker System - with DSLR Dovetail & Solar Filter - ES-iEXOS-100-02

The iEXOS-100-2 PMC-Eight Equatorial Tracker System is a complete astronomical computerized Wifi or Wired GOTO Equatorial Tracker with integrated PMC-Eight electronics suitable for attaching Small Telescopes or DSLR Cameras attached to the Explore Scientific DSLR Camera Dovetail Assembly.


  • Integrated Explore Scientific PMC-Eight™ system that transcends the industry standard single processor by utilizing eight CPUs that operate independently of one another to focus on defined functions, which results in superior responsiveness, efficiency, reliability and astoundingly fast timing intervals.
  • Clutched dual-axis worm gears with quiet precision stepper motor belt drives.
  • Intuitive ExploreStars app, which is available for Apple, Android and Windows tablets, that makes it simple to operate the GOTO system. Through it, users can quickly align their telescope, navigate the stars and learn specifics about tens of thousands of celestial objects.
  • Clutched RA and Declination axes are smooth and allow for precise balancing which makes the process of repositioning your telescope efficient.
  • Polar alignment sight hole through the RA axis and precise altitude control for fast alignment without polar scope.
  • Battery pack powering the PMC-Eight™ system uses 8 C batteries and is secured in a bracket on one of the tripod legs when in use.
  • DSLR Camera Dovetail Plate.
  • Sun Catcher Solar Filter.
  • Two 1 kg counterweights included.
  • Glow-in-the-dark markings on mount and tripod.

    Use with the free ExploreStars App for Tablets (Windows, Android, Amazon and Apple), or with the free ASCOM Standards Compliant PMC-Eight ASCOM driver and the ASCOM POTH Client from Explore Scientific (either wired or wireless) to work with virtually any sky software that supports ASCOM. Tablet or computer must be purchased separately.

    The iEXOS-100-2 utilizes a proven German equatorial mount design and Explore Scientific’s revolutionary PMC-Eight™ Precision Motion Control system to flawlessly navigate the night sky and track objects as they journey across it. This combination provides superior observing and imaging performance without a prohibitive price tag.

    GOTO systems play an important role in the world of amateur astronomy because they ensure users spend less time searching for particular objects and more time observing and imaging. The PMC-Eight with its versatile connections supported with free to download apps for Windows computers or Android and iOS tablets only (tablets must have a screen of at least 7 inches), or through the free to download ASCOM PMC-Eight driver and POTH Client to connect to your favorite ASCOM Compliant Astronomical Software, can allow you to control the telescope from a few feet away or by communicating computer-to-computer with an Internet connection from virtually anywhere in the world. 

    One of the standout features of the iEXOS-100-2 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.

    Before you can track an object, you need to find it, and that objective can be daunting when you’re faced with a vast expanse of inky black sky or a bright city sky. The iEXOS-100 puts a powerful GOTO system in your arsenal of astronomical tools that takes the frustration out of navigating the night sky.

    This integrated version of Explore Scientific’s PMC-Eight™ system transcends the industry standard single processor by utilizing an 8-core microcontroller with eight CPUs that operate independently of one another to focus on defined functions. This delegation of tasks among the processors results in a system that offers superior responsiveness, efficiency, reliability and astoundingly fast timing intervals for smooth image acquisition and accurate tracking.

    Although it is internally complex, the GOTO system can be easily operated from your own Apple, Android or Windows tablet using the ExploreStars app, which has an intuitive nature that makes it simple and quick to align your telescope, navigate the stars and learn specifics about tens of thousands of celestial objects. This dynamic app is fueled by a database that is routinely updated to ensure it remains a relevant resource.

    Our commitment to creating a streamlined GOTO mount is obvious in other design choices. The iEXOS-100-2 has smooth locking clutches that will let you quickly reposition your telescope from one side to the other and an altitude knob for smooth height adjustments. The mount base includes a small polar alignment tunnel that allows users to roughly align their observing setup with Polaris. It also has a simple bubble level that comes in handy when stabilizing your tripod.

    Other features include a bracket for holding the battery pack, which powers the PMC-Eight system through 8 C batteries (not included); two 1 kg counterweights for balancing; and glow-in-the-dark markers on certain points of the mount and tripod so you can stay oriented with your setup at night. The mount is designed to hold up to 19 lbs (scope, accessories, and counterweights added together).

    The mount weighs 9.45 pounds (4.29 kg), while the lightweight Travel Tripod and accessory tray weighs 5.5 pounds (2.5 kg). The Travel Tripod, when collapsed is 27.25 inches (69.21 cm) tall.

    Connect by wire, WiFi, or Bluetooth®* to navigate the night sky and track objects with this integrated GOTO system that pairs a proven German equatorial mount with our revolutionary PMC-Eight™ motion control system.

    Explore Scientific Dovetail Plate

    The Explore Scientific Camera Dovetail Plate is designed to make it easy to attach a camera to a standard astronomical tripod Vixen-style saddle plate.

    The Camera Dovetail Plate has three slots which can be used to mount a camera.

    The device comes with a standard ¼-20 bolt installed in one of the slots. Installed onto the ¼-20 bolt is a 3/8-16 adapter, which is a European standard. To use the ¼-20 bolt, simply unscrew the 3/8-16 adapter. Be sure to put it a safe place in case you ever need to use it.

    The Camera Dovetail Plate also comes with a spring-loaded pin, which is used on some cameras and camera foot plates.

    To move the ¼-20 bolt from one slot to another, ensure the 3/8-16 adapter is removed, then slide the bolt to the end of the slot that is wider. Using the swivel handle on the bolt, unscrew the bolt. It may be helpful to press down from the top while unscrewing from the bottom. Once the ¼-20 bolt is removed, place it in the desired slot, where the end is wider, and screw it in.

    To move the spring-loaded pin, use a 4 mm Allen (hex) wrench to unscrew the set screw. With the set screw removed, carefully turn over the plate to remove the small spring and pin. Be careful to not lose the dark-color spring or pin.

    Select the hole where the spring-loaded pin needs to be installed and put the pin in the hole. Be sure to put it in with the thin side down and ensure that the pin aligns with the hole so the silver tip is sticking out. The flange should be on top. Place the spring into the hole, then install the set screw. Do not over tighten or the pin will no longer be spring-loaded.

    To install a camera, align the ¼-20 screw to the mounting hole in the camera or lens, then screw in the bolt. Tighten as needed. If additional pressure is needed, tighten the spring-loaded pin.
