The Vixen 25083 consists of the AZ103S, a 4” f/8 refractor with a 3-element objective and rear field corrector lens, and the SXD2 GoTo equatorial mount with a Star Book Ten controller. This is a great intermediate to advanced level equatorial telescope package with dual-axis drive and computerized GoTo electronics. Perfect for both astrophotography as well as visual use, you’ll love the tablet-style controller and the beautiful contrast of this Japanese made 103 mm refractor.
About the AX103S Refractor Telescope
The Vixen AX103S is a 4” f/8 Refractor that features a three element objective lens with an ED lens in the center. This reduces chromatic aberration and yields high contrast images. Combine this superb lens set with the rear field corrector lens to yield clear images to the edges of the field of view. "Precision Multi-Coating" is applied to the lenses of the AX103S, assuring high light transmission. Astronomy Magazine states "Its superb optics allow high magnification views". Sky at Night Magazine states: "With its excellent build quality and rich feature set, we thoroughly recommend this system if you are looking to upgrade from your current setup". Manufactured in Japan and covered by a 5 Year Warranty. Includes 7x50 finder, dovetail, tube rings, carry handle, and a flip mirror.
About the Vixen SXD2 Mount
Vixen has reworked the design and manufacture of its innovative SXD Mount, creating the SXD2 German Equatorial Mount. The SXD2 Mount has a greater loading capacity and is more rigid enabling a more steady platform for astrophotography. The quieter stepping motors ensure you of smooth, quiet slewing with quick response to commands. The Star Book Ten, available previously on the SXP Mount, features an intuitive Star Chart Go-To System on a high definition LCD Screen. Features include night vision screen, hibernate mode, VPEC and PPEC, and optional built in auto guider. Both the RA and DEC Axes are made of sturdy steel with brass wheel gears. This enables the mount to carry loads of up to 50 pounds (including counterweights) for astrophotography.
Smooth RA and DEC Movement: The inside of the new SXD2 is very different from the previous SX Mounts. Bearings have been added to the shafts of t he RA and DEC axes and the screw gear shafts. The worm screw gears are inspected for strict concentricity and are lapped in the whole-circle for smooth movement.
Increased Loading Capacity: Both the RA and DEC Axes are made of sturdy steel with brass wheel gears. This enables the mount to carry loads of up to 50 lb. (including counterweights) for the visual observer and 33 lb. for astrophotography.
STAR BOOK TEN & HAL-130 Tripod Features
The STAR BOOK TEN is the most advanced astronomical hand controller available and is recommended for anyone interested in exploring the night sky. The innovative STAR BOOK TEN hand controller offers astronomical navigation with a large full-color High Definition LCD screen! The color screen is a detailed star chart that acts as a navigational and GOTO guide for the mount.
The screen can be displayed with monochromatic red light in order to maximize the accommodation of your eyes to darkness. The operating keys can also be lit in red.
Hibernate Mode: After selecting to continue the current setup at the initial screen, you can break and restart your automatic slewing and tracking of the mount by just flipping the power switch, if the mount is still in place, without loosening the R.A. and DEC clamp levers.
Different Tracking Rates: The motion of the moon, the sun, planets and comets have different tracking rates than the stars. The STARBOOK TEN moves the mount at different rates, automatically, dependent upon the target object.
Artificial Satellite Watching: The STARBOOK TEN has a menu to find and track artificial satellites by entering the orbital elements of the satellites. the ISS and named satellites are pre-registered.
The HAL130 Tripod provides ample stability and has no wobble points in its design. The HAL130 has a large base to carry the SXD2 mount. The tripod extends from 32" to 51" (81cm to 130cm) and weighs 12 lb.(5.5 kg).
