The Software Bisque Paramount MEII is high precision German equatorial mount (GEM) that is designed to deliver outstanding pointing, tracking and stability for amateur or professional astronomers. The Paramount ME II's  precision mechanics, when used in conjunction with TheSkyX Professional Edition PC software, creates a formidable imaging system that can help you achieve your observing and/or imaging objectives. 

The main features of the Paramount ME II include:

  • The ME II weighs 38kg (84lb) and can carry a total of 109kg (240 lb) total instrument capacity (218kg/480 lb total carrying capacity with counterweights)
  • Belt-driven gears offer virtually zero backlash
  • Maximum 7 arcseconds "Peak-to-Peak" periodic error before PEC
  • Clutchless design maintains T-Point assisted pointing accuracy
  • 30 arcsecond or better all sky pointing accuracy with T-Point and Super Model mount modelling software
  • Two port USB 2.0 hub on the Instrument Panel
  • Completely redesigned Control System (MKS 5000) featuring 2" USB computer to mount interface
  • Calibrated Polar-Alignment-Adjustments
  • Paramount 3" Losmandy-style VersaPlate (clamp)
  • Through the mount internal cabling for no cable snags or tangle
  • All internal electronics and wiring.
Please note: No tripod or pier is supplied with the Paramount ME II

    Hours past meridian (track and slew)

    Maximum slew speed*

    4 degrees per second in right ascension and declination*

    *Maximum Slew Speed Disclaimer 

    The factory default of 80% maximum slew rate works well with most payloads over a wide range of temperatures. Paramount mounts can slew at the maximum slew rate with a balanced payload that is approximately 50% or less of the total rated capacity, when the spring plunger pressure adjusted to factory standards at moderate ambient temperatures. 

    As the mass of the payload increases, and/or the ambient temperature decreases, the mount may not be able to maintain maximum slew speeds. When near or above the stated capacity of the mount, or during cold temperature operation, slower maximum slew speeds and lower accelerations will be required.
