Designed as a complement to the AXD2 equatorial mount, the AXJ mount offers outstanding durability and precision.

The AXJ mount can also be used on AXD-TR102 tripods with an adapter. Periodic errors on mounts are usually measured and corrected by the user. Unlike the old StarBook controller, the STAR BOOK TEN controller saves these errors permanently. The periodic error of the mount is measured in the factory (total of 12 points per 30 degrees worm gear) and corrected before delivery. This is known as V-PEC and functions automatically as soon as you use the mount. It delivers an accuracy of +/- 4.0 arc seconds. You can increase the tracking accuracy further by saving your own recorded periodic errors.

Vixen uses a new Belt-drive system in the AXJ mount. The gear drive was replaced with a toothed belt drive. This gives the mount a quicker reaction time and lower backlash. It also helps to minimize noise. The 6x20 polar finder scope is pre-installed. This allows the user to configure the polar alignment (for both the northern and southern hemispheres).

The polar finder scope has a variable illuminated reticle with an automatic power-off function. The brightness can be adjusted in 8 levels so that the user can configure the desired brightness.SETTING ACCURACY OF LESS THAN 3 ARC MINUTES. The darkfield illumination (red LED) turns on when the push button is pressed. The reticle also lights up in red so that the observer can recognize and align stars in the background of the reticle. The light turns off automatically after a few minutes to save battery power.

2 bearing sets (4 pieces) are used for the shaft of the RA axis. Thanks to the newly developed EQ design, the ZXJ mount has a higher load capacity of 22 kg. As the motors, worm shaft and worm gear are located in the lower part of the mount, fewer counterweights are required than with conventional mounts. The STAR BOOK TEN controller is a modern control system with a high-resolution color monitor.

The STAR BOOK TEN system contains more than 272,000 celestial objects, including 260,000 stars from the SAO catalog, 109 Messier objects, 7840 NGC objects and 5380 IC objects, as well the soon, moon and planets. Objects can be accessed by name, and information such as images and data can be defined separately.
