Explore Scientific designed their IEXOS-100 PMC-Eight Equatorial Go-To Tracker System Mount to provide users with a precision platform built to support small-to-medium sized optical tubes and astrophotogrphy and imaging rigs.
ES continues their commitment to user-friendly gear with the PMC-Eight motor drive system that uses micro-stepper motors and a direct-drive belt connection between the drive shaft and motor to ensure accurate and smooth tracking for extended periods with minimal vibration and zero backlash. The entire PMC-Eight software suite is offered as open-source coding so users are able to tweak the system to their personal preference and share with a growing community of enthusiasts.
Keeping up with the latest technology, the common wired control system is replaced with a wireless antenna for remote control from Windows or Android/iOS smartphones and tablets running the ExploreStars app. It has 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. Like the coding for the motor drive system, the app is open source as well, so it can likewise be customized and those modifications shared. A non-volatile memory and Real-Time clock preserve settings, including backlash correction and Periodic Error Correction (PEC), when the system is turned off and power is disconnected.
