Vixen AXD2-AX103S-P 103mm f/8.0 APO Telescope - ES36943-SO
Best for serious astrophotographers who demand a perfect imaging platform with user-friendly functions that allow for comfortable operation.
The quad element AX103S apochromatic system that features SD glass for uncompromising optical performance, comes mounted on a sophisticated AXD2 atop a steel pedestal.
Superior performance and ease of use.
Versatile functions and high level of accuracy demanded by advanced astrophotographers and ease of use appreciated by novice astronomers are merged into the AXD2 mount with STAR BOOK TEN controller.
AX103S optical tube assembly.
The advanced optical design produces crystal-clear, sharp and high contrast images with no trace of false color.
The star images are as small as 20 microns at the edge of the imaging field.
A premium AS coatings applied to each surface to the lenses enhances visible light transmission to 99.5% on any single surface (400nm - 700nm) and assure extremely high light transmission.
Vixen's flagship equatorial mount.
The AXD2 mount is designed for both superior performance and ease of use.
The revolutionary advanced star chart go-to navigation controller STAR BOOK TEN is the best companion for your observing sessions.
Polar alignment scope.
A 6x20mm polar scope with illuminated reticle is provided with the AXD2 mount.
With the help of a built-in Polaris position scale, it achieves an easy and accurate polar alignment within 3 arc minutes in the northern hemisphere.
STAR BOOK TEN star chart go-to navigation controller.
The STAR BOOK TEN features an 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.
