  • Maximum of 7 arc seconds of periodic error before correction.
  • Easily run your wires through the mount, no disassembly required!

Bigger, Stronger: The Paramount ME II

More robust in every way, the Paramount ME II has a remarkable weight capacity of 240 pounds while weighing in at a moderate and manageable 84 pounds. Increased bearing size, a larger counterweight shaft diameter and, of course, a far greater weight capacity make the ME II a more heavy duty follow up to the legendary Paramount ME.

As expected with every Software Bisque mount, the ME II is strong and smart. Borrowing from the MX mount design, you can now run you equipment cables through the mount - with no disassembly required. The instrument panel also includes 2 USB ports so you're sure to be able to connect your guiding accessories with ease.

Always striving for perfection, the Paramount MEII's belt driven motors are nearly backlash-free. A maximum of 7 arc seconds of periodic error, before correction, provide remarkable slewing accuracy and clutch-less gears maintains T-Point's pointing accuracy.

On-Axis Encoder Options

This mount is available with either single or dual on-axis encoders. Unique from the servo encoders that control the input of mount movement, on-axis encoders will read the output of actual, rather than calculated, mount movement. This additional readout will vastly improve pointing and tracking accuracy as well as make up for the majority of any backlash or periodic error that are a natural part of mechanical movement. The axis will also always know it's position which means the need for homing is eliminated.

Cost to upgrade each axis is $4000. Please indicate in the comments section of your order or email if you would like the RA axis or both axis upgraded and your order will be adjusted accordingly. This is a factory installed option and it is strongly suggested that you request the upgrade at the time of your mount order to avoid any additional shipping fees in sending the mount back to Software Bisque.

Delivery times are extended for orders with on-axis encoders. Customers waiting on encoders will be updated as Software Bisque releases information.

Product Questions

If we opt for the on axis encoder upgrade, is that something that comes installed or do we have to do that? Also is there additional time involved for that or is that something already in stock?
