This AX103S Refractor Telescope bundle from Vixen Optics includes four main components, a telescope, a tripod, a mount, and an electronic hand controller. These items are combined to create a capable and user-friendly rig for celestial object viewing.
The AX103S Refractor Telescope is an apochromatic f/8.0 refractor with a focal length of 825mm, an aperture of 103mm, and a Quad Element Design. Its three-element objective is complemented by a central fourth lens made from "Super Low Dispersion" glass. This optical design helps reduce chromatic aberration while delivering high-contrast imagery. Precision Multi-Coating is applied to the lenses in order to enhance light transmission and reduce internal reflections that could otherwise reduce overall image quality. A rear field corrector lens is also installed to help further ensure a crisp, high-contrast field of view that is virtually free of false color.
The AX103S weighs 10.0 lb and is fitted with 115mm mounting rings. A dovetail plate is provided, as well as a carry handle. This bundle includes Vixen's 20mm SLV Series 1.25" Eyepiece, a 5mm SLV Series 1.25" Eyepiece, plus a flip mirror diagonal to enable accurate, visual framing and focusing for astrophotography. The flip mirror diagonal can be configured with one of the included eyepieces and a camera. On the AX103S, the 20mm eyepiece provides 41.25x magnification, while the 5mm eyepiece provides 165x magnification.
Vixen's Sphinx SXD2 Equatorial Mount provides a precise and stable motorized mount for long observation sessions, or long-exposure astrophotography. Dual stepper motors provide smooth and virtually vibration-free tracking that run at up to 250pps. Its full-circle brass wheel gear allows the mount to track over extremely long periods with little tracking error.
This Sphinx comes with the Star Book Ten (SB10) computerized hand controller that is loaded with a database of 272,342 celestial objects such as the Moon, Sun, and planets, plus astronomical catalogs including SAO, NGC, and Messier. The SB10 has a 5" 800x400 resolution LED backlit TFT LCD screen that displays star charts, maps, as well as menu options. To aid set-up, there is a built-in 6x20 polar alignment scope that is set inside the mount. It has an 8° wide angle field of view and an illuminated reticle. The Polaris guide scale, for use in the Northern hemisphere, is accurate through the year 2025. An Octant 4-star pattern is also set on the reticle for use in the Southern hemisphere.
The provided tripod on which to rest the telescope, mount, and hand controller is Vixen's HAL 130 tripod. Its adjustable height allows the user to set the position of the telescope to their liking for easy and comfortable viewing. The top of the tripod is powder-coated with a durable finish that resists chipping, flaking, and fading. The tripod is collapsible for convenient storage and portability.
Also included in this bundle is Vixen's 7x50 Illuminated Finderscope to aid in centering observed objects, and a half pillar which contributes approximately 8.0" of additional height to the mount. This pillar provides clearance when attaching a DSLR to the rear or the telescope, and increases comfort for taller observers as well.
