Refined engineering and years of mount development have led to several additional mount features for the Paramount MyT EQ. Through-the-mount cable management helps keep your set-up organised and tangle-free. A rotating mount base allows AZ adjustments without affecting the mount's altitude. Red lights provide a soft glow under the mount to allow for ease of adjustment at any moment. This light can be turned off as well as your viewing or imaging session gets underway. The clutch-free worm block design maintains the mount's physical orientation to increase mount pointing and tracking accuracy, while a mechanical switch on each axis will disengage the worm from the gear while still balancing the payload.

Software plays a significant role in the functionality of your mount set-up, and Software Bisque has you covered with a full suite of mount and camera control software. Included with your MyT mount are the TheSkyX Professional Edition, a full-featured planetarium-style software that offers a beautiful interface for mount control. Camera Add-On software allows for the camera, focuser, filter wheel and SBIG adaptive optics control. TPoint software with SuperModel and ProTrack provides professional-level telescope pointing correction. All software included is multi-licence, allowing for installation on up to 6 machines and can be installed on either Mac or Windows operating systems.

Encoders FAQ

What is the difference between motor-based incremental encoders and on-axis absolute encoders?

Paramounts equipped with on-axis absolute encoders know where they are at all times.  Paramounts with incremental encoders (or motor-based encoders) know only how far they have moved since they were initialised using a nightly process called homing.

The crucial additional difference is that the on-axis absolute encoders are fitted directly to the mount axes, bypassing the worm drives.  Paramounts with incremental encoders are fitted to the worms instead, which means that with incremental encoders alone, periodic errors in the worm drive show up in the tracking.  These mounts must be calibrated and corrected using periodic error correction (PEC), which measures and records the repeatable gear train errors and removes them.  (TheSky features advanced, multi-harmonic PE detection and PEC calibration that minimises periodic error in mounts with incremental encoders.)

For mounts with incremental encoders, homing re-zeros the encoders when precise sensors on each axis are reached. From then on, the incremental encoders are, in effect, delivering absolute readings.

However, the crucial additional difference remains: the incremental encoder system is behind the worm drive, and periodic error correction is still required to get the best out of the RA tracking.

High-resolution on-axis absolute encoder technology is significantly more expensive than incremental encoders.

Are on-axis absolute encoders right for you?

The short answer is, “It depends.”

On-axis absolute encoders eliminate periodic error and enable the mount always to know where “home” is.

That’s convenient and expedites setup for an evening of imaging. However, with Paramount's, the periodic error is already very low, and after a one-time training, it becomes negligible. Moreover, Paramount’s included Homing software homes in only 15 to 60 seconds.

So, at least with Paramount, the periodic error is practically non-existent, and homing is a breeze.

What about pointing and tracking?

Without encoders, Paramounts routinely deliver 5-to-10-minute unguided exposures; many have reported 20 minutes. Also, without encoders, Paramounts produce all-sky pointing accuracies at or below 30 arcseconds RMS.

Absent Paramount’s exceptional software, that performance would not be possible. Operating in conjunction with TPoint™, ProTrack™ continuously updates the mount’s position across both axes to correct system-wide tracking errors, including tube flexures, atmospheric refraction, polar misalignment, harmonic errors from mis-centred encoders and/or worm gears, and more.

On-axis absolute encoders alone cannot correct these errors, which exist with all telescopes. A properly applied telescope model is necessary to achieve superior pointing and tracking.

So, are on-axis absolute encoders right for you?

Perhaps, if you want to enjoy the conveniences mentioned above, and for many, that’s enough.

That said, the optional on-axis 26-bit Renishaw absolute encoders with 0.02 arc second precision are the finest available and operate in temps as low as –40° C.

• Paramount’s unequalled pointing and tracking wouldn’t be possible without its TPoint™ and ProTrack™ software.
• By employing TPoint’s calibration and telescope modelling tools, you’ll enjoy all-sky pointing accuracies at or below 30 arcseconds RMS. Nothing outperforms that (TPoint’s details).
• Operating in conjunction with TPoint™, ProTrack™ continuously updates the mount’s position across both axes to correct system-wide tracking errors, including tube flexures, atmospheric refraction, polar misalignment, harmonic errors from mis-centred encoders and/or worm gears, and more.
