• 30-pound payload capacity
• Dual-axis low-cog DC servo motors
• Dual motor encoders improve tracking and location accuracy with reduced vibrations
• 7-77° latitude range
• Uninterrupted tracking below meridian to enable observation from a raised location such as a balcony or hilltop
• Integrated 12″ counterweight bar with one 12-pound counterweight
• Vixen-style CG-5 dovetail saddle

• 40,000+ object database
• 100 user-defined programmable celestial or terrestrial objects
• Enhanced information on over 200 objects
• Nine slew speeds: 4°/sec, 2°/sec, 1°/sec, 0.3°/sec, 32x, 16x, 8x, 4x, 2x
• Three tracking rates: Sidereal, Solar, Lunar
• Multiple alignment procedures: Two-star, One-star, Solar system, Quick-align, Last-align
• Sky Tour Mode: System seeks out the best objects for the date and time and automatically slews to them
• Identify Mode: Use to identify an unknown object in the field of view, or to find other celestial objects that are close to where the user is viewing
• Anti-backlash compensation: Trains out the intrinsic play between gears for more precise slewing and tracking
• Permanent Periodic Error Correction (PPEC): System learns its internal tracking errors and improves over time for more precise tracking, requiring fewer corrections
• Built-in instructions guide you through the alignment procedures
• 4-line, 18-character LCD display with a 19-summary fiber-optic backlit LED keypad
• RS-232 comm port
• Supports English, French, Italian, German, and Spanish

• Database details:
• Solar system: Seven planets, Moon, Sun, and Pluto
• Custom lists of all the brightest stars, double stars, variable stars, and asterisms
• Custom lists of galaxies, nebulae, and clusters, as well as the complete Messier catalog and select NGC objects

• Tubular stainless steel legs
• 2″ leg diameter
• 44-64″ height-adjustment range
• Center tray holds 1.25 and 2″ eyepieces and locks legs in place for greater stability and vibration reduction
• Removable hand controller holder can be moved to avoid cord wrap during long observation sessions
• Weight: 18 pounds

• 200mm (8″) aperture is ideal for lunar & planetary viewing with the ability to resolve bright deep sky objects
• Fast f/5.0 focal ratio ensures bright and clear views with a wide viewing angle
• 1000mm focal length has a high magnification potential
• Newtonian reflector optical design is lightweight and easy to use despite its large aperture
• Fully coated optics increase light transmission, and improve contrast and color rendition
• Resolution: Rayleigh: 0.7 arcsec; Dawes Limit: 0.58 arcsec
• Secondary mirror obstruction: 2.25″; 28% by diameter;7.81% by area
• Sturdy rack-and-pinion focuser

• Optical tube only, mount and tripod required for proper use
• Vixen-style CG-5 dovetail bar is compatible with a wide array of mount heads
• Weight: 14 pounds

• 20mm focal length produces 50x magnification
• 1.25″ barrel diameter
• Accepts most astronomical eyepiece filters
• Fold-down rubber eyecup prevents peripheral light interference

Finderscope:

• Relatively low 9x magnification provides a wide field of view for fast manual acquisition of subjects and easy star-hopping navigation
• 50mm objective keeps the overall weight low
• Mounting bracket included
