The AXJ-A103S package comes with the quad element AX103S apochromatic system that features SD glass for uncompromising optical performance, the pinnacle of this aperture class. The mount comes with a sturdy but lightweight ASG-CB90 tripod made of carbon fiber.
The three element objective lens including the center SD glass produces crystal-clear, sharp and high contrast images with no trace of false color. Besides, the star images are as small as 20 microns at the edge of the imaging field with the built-in field corrector lens. 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.
The AXJ mount equipped with ultimate periodic correction VPEC provides precise tracking as accurate as +/- 4 arc seconds or less. The VPEC works automatically as you use the AXJ mount. The belt drive system reduces backlash dramatically and makes the motor noise quieter. A quick and stable motor response has been achieved. The AXJ mount carries a maximum loading weight of 22Kg.
The STAR BOOK TEN 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.
The ASG CB90 is a compact and lightweight tripod which is constructed of durable carbon fiber legs. Also, the tripod head, leg extension part and leg brace have been reviewed completely to realize a highly stable tripod for the AXJ mount.
