Latest Model with Starbook Ten and NEW PFL Polar Axis Scope.

Vixen Japan's new high precision SXP-PFL German Equatorial Mount is an excellent choice for serious visual astronomers and astro-photographers seeking the latest in Japanese design and engineering. 

The Vixen SXP mount comes with Star Book Ten controller for manual or computer controlled observation or astrophotography.

Using the same high precision pulse stepper motors as the top of the range AXD mount, the new SXP-PFL brings a new level of performance to the mid-range Vixen mount family. The SXP-PFL is quieter and smoother in its tracking than the SX and SXD mounts and the increased precision of the motors allows for improved performance for long-exposure astrophotography.


Product Features

  • New Star-Book TEN latest generation Vixen handheld controller with high resolution screen and extensive feature set.
  • High-precision pulse stepper motors deliver accurate, quiet and smooth movement.
  • High precision 72mm CNC machined brass RA and DEC gear wheels with 180 teeth for accurate tracking.
  • Uprated carbon steel RA and DEC shafts supported by a combination of 15 bearings.
  • Declination body acts as part of the counterweight system reducing the amount of additional weight carried on the counterweight shaft.
  • Star-Book TEN controller enables permanent periodic error correction data to be saved.


NEW Vixen PFL Polar Axis Scope

The new Vixen PFL Polar Scope improves on the performance of Vixen's original polar scope. 

  • In the northern hemisphere, the polar axis is aligned by placing three bright stars in the 
  • specified positions. 
  • No need to set hour angle. 
  • The built-in scale is illuminated in red, so that it is clearly visible in the night sky. 
  • The brightness of the dimmable illumination can be adjusted in 8 steps. 
  • When pressing the illumination button, the scale is illuminated for one to two minutes. 
  • Power will automatically turn off after one to two minutes to prevent unnecessary power 
  • consumption.

Vixen Star-Book Ten

This latest generation of Vixen’s computerised GO-TO controller is named Star Book Ten* and has been designed to guide you to a database of more than 270,000 objects in the sky as quickly and easily as possible. The new controller includes many new features as well as a host of updates and improvements to the existing Star Book platform. One of these new features is the so-called “see to” system which shows a preview of a chosen object on the controller screen before the GO-TO sends the telescope to that object.

* The Japanese word “Ten” means “The Heavens” 





High resolution TFT LCD screen
The controller has an LED-backlit 5” LCD display with 0.3 megapixel (800x480) wide format resolution. Combined with the onboard 2D graphics acceleration of the Renesas SH7764 processor, this means that Star Book Ten delivers fast and smooth scrolling with clear graphics and text at all zoom levels.

Night vision and deep dimming
The addition of a night vision mode and red keypad backlighting make this a truly observer-friendly controller. The keypad and screen backlight levels can be controlled independently. The LED backlighting of the LCD panel means that the screen can be “deep dimmed” to allow full colour display use whilst protecting the user’s night vision.

Hibernate mode
This allows the user to start and stop either an imaging or observing session by simply switching the mount off and on again. The hibernate mode works only if the mount is not moved and the two axes are not manually repositioned.

Huge object database
A database of more than 270,000 celestial objects including Messier, NGC, IC objects and the SAO star catalogue is built in and can be searched by name or number. User defined objects including comets and artificial satellites can also be added.

Multiple PEC modes
Whilst Vixen includes an individually adjusted RA PEC at the time of manufacture, the controller allows the user to add an additional layer of mount training data for the RA and DEC axes.

Multiple object tracking rates
The motion of the moon, the sun, planets and comets can all be tracked.

Artificial satellite tracking
Star Book Ten includes data on the most popular artificial satellites including the International Space Station (ISS). Other objects can be added to the database by the user.

Expansion board (optional)
To provide added features for the serious astro photographer, the controller can accept an optional expansion board. This includes a PAL/NTSC video input which can be used to take still or video images to a memory card in the onboard SD card slot. When used with a guide scope and camera, the expansion board provides “closed loop” autoguiding, controlled by the Star Book Ten itself.
