Vixen Telescope AXD2 equatorial mount Description
-
Vixen's flagship equatorial mount that is designed for both superior performance and ease of use.
Avid astronomers will find that the high performance and precise tracking of the AXD2 mount will raise their level of astrophotography. With its ease of use and superior performance, the AXD2 mount offers even novice astronomers the opportunity to be a successful astrophotographer. No matter how you are involved in astronomical observing or astrphotography, the superior interface of the STAR BOOK TEN lets you operate the AXD2 mount without any difficulty.
-
Innovative, elegant and functional design of the AXD2 mount.
The flattened side-forms with minimal protrusions looks the AXD2 mount elegant and functional in combination with its white and silver colored external appearance.
-
STAR BOOK TEN star chart go-to navigation controller.
The AXD2 equatorial mount PFL comes with STAR BOOK TEN which features intuitive 'Star-Chart Go-To' system with high definition color LCD display. The position of the telescope, the target and other useful information are displayed on the screen in detail. The night vision feature illuminates the whole screen in red, if applied, and will limit the brightness to the observer's eyes.
-
Sturdy axes and lightweight body.
The structure of German equatorial mounts has been throughly examined in order to create the sturdy but lightweight AXD2 mount. The A7075 super-alloy, which is the strongest material among the group of aluminum alloy, is used for the R.A and Dec axes. The tension of the A7075 super alloy is stronger than titanium a lightweight material of high strength. Its specific gravity is 38% less than titanium. Both axes are as thick as 50mm in diameter.
-
Large wheel gears strengthen tracking precision.
The number of the gear teeth has been increased with use of large wheel gears in diameter to increase the mechanical accuracy for precise tracking with the ultimate stability.
-
21 pieces of bearings.
The rotational parts of the AXD2 mount have 21 pieces of bearings in total. This provides extremely smooth motion for tracking and slewing to the target objects.
-
High response pluse motors.
Vixen selected accurate pulse motors for better response which enable the AXD2 mount to fully realize its performance potential. A newly developed micro-step motion control system generates high speed 400 pulse per second to deliver surprisingly smooth tracking free of oscillation in any slewing speed.
-
Minimum backlash
Vixen's micro-step motion control system accurately works the pulse motors from low speed to high speed. This eliminates the need for reduction gears in the motor gear train and dramatically decreases backlash of the gears.
-
Ultimate VPEC periodic error correction achieves within +/-2.8 arc seconds tracking accuracy.
The periodic motion of the AXD2 mount has been measured precisely and stored in the nonvolatile memory inside the mount at Vixen's factory before shipment. This is called VPEC. The VPEC works automatically as you use the mount. It provides tracking as accurate as +/-2.8 arc seconds or less. You will be able to raise the tracking accuracy further by adding your own recorded PEC as the occeasion demands.
