Software Bisque will offer optional on-axisencoders for the Paramount ME II; the estimated ship date at this time islate 2014.  

The tentative (and subject to change) detailsabout optional on-axis encoders are below:

Optional component for the right ascensionaxis and/or the declination axis.

Will allow all sky RMS pointing accuracies(with TPoint modeling) to five (5) arcseconds or less.

Periodic errors in the worm gear/main geardrive mechanics are virtually eliminated, and periodic error training is notrequired.

The axis that has the on-axis encodersalways knows its mechanical orientation so that no homing or mountsynchronization is necessary.

The Paramount ME II's right ascension anddeclination axes are already designed to accept on-axis encoder hardware andcabling.

Paramount ME IIs purchased before theon-axis encoders are available must be returned to Software Bisque for on-axisencoder installation.  

In other words, on-axis encoders must be installedby authorized Software Bisque personnel and cannot be installed bythird-parties.

The estimated cost of the hardware andinstallation is $3,000.00 per axis.

Software Bisque will email all registeredParamount ME II owners when they are available.

On-axis encoders will not beavailable for the Paramount MXRobotic Telescope Mount or the earlier generation Paramount ME RoboticTelescope Mount.

While on-axis encoders have many advantagesas described above, they should not be considered the "panacea"for taking long, unguided photos. 

Fortunately, TPoint's ProTrack (a softwaretechnology exclusive to Paramount mounts)compensates for external factors such as optical tubes that bend 

anddifferential refraction that conspire to degrade pointing and tracking accuracyand cannot be "fixed" with on-axis encoders.
