This ED115S 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.
Vixen's ED115S Refractor Telescope is an apochromatic refractor with a focal length of 890mm and an aperture of 115mm. It combines the assets of "Super Low Dispersion" glass in the objective lens and a fast f/7.7 focal ratio to deliver clear, wide-field deep-sky imagery. The SD glass lenses produce a crisp, high-contrast field of view that is virtually free of false color. They are capable of focusing the visible spectrum with accuracy and chromatic aberrations are minimized as well.
The ED115S is stable and weighs 8.0 lb. It is fitted with 125mm 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. On the ED115S, the 20mm eyepiece provides 44.50x magnification, while the 5mm eyepiece provides 178x magnification. The flip mirror diagonal can be configured with one of the included eyepieces and a camera. When an interesting object has been located, the Vixen Dual Speed Focuser offers a quick, or a fine 1/7th speed focus for critical observation.
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, a compression ring that allows the use of 2.0" eyepieces, 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.
