About this product

Model:  vixen_sxd2_pfl
Part Number:  25101

Heavy duty but portable astro imaging and observation platform

The Vixen SXD2 PFL mount comes with Star Book Ten controller for manual or computer controlled observation or astrophotography.

A ‘deluxe’ version of the SX2 mount platform, the SXD2 PFL is based around the same compact, lightweight design of the SX2. 

The SXD2 has a higher payload capacity than the SX2 at 15kg (33lb).


Smooth & accurate tracking motion
The mount has high quality bearings on the RA and DEC axes to reduce load on the motors and to make the motion of the axes as smooth as possible. When the mount is well-aligned and used in conjunction with a third party autoguider, it offers exceptional tracking performance with the heaviest of astro imaging payloads.


High grade materials
The high grade steel chassis provides stable and accurate RA and DEC axes. The placement of the motors in the lower part of the mount casing allows them to form part of the counterweight package, reducing the need to add additional counterweights to balance the scope.

High quality worm gear
The all-new brass worm gears allow smooth movement through the whole 360° motion of the mount. Combined with the latest high-performance stepper motors, the SXD2 offers the keen amateur astrophotographer the perfect platform for long exposure imaging.


Polar axis scope
The polar scope PF-L with built-in dark field illuminator is supplied as standard with the SXD2 mount and is mounted in the RA body. Vixen’s excellent reticle design and precise RA axis/polar scope alignment allow for precision polar alignment. No hour angle setting is required, making set up quick and simple.


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.
