Explore Scientific designed their iEXOS-100-2 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 astrophotography 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
code so users can tweak the system and share their preferences with a
growing community of enthusiasts.
Keeping up with the latest technology, the common wired control system
is augmented with Wi-Fi and Bluetooth for remote control from Windows or
Android/iOS tablets running the ExploreStars app. It has a database of
over 70,000 objects and an intuitive user interface controlled with the
device's touchscreen. Multiple alignment procedures, slew and tracking
rates, and customized guided tours enable 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, so it can 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.
