Sky-Watcher Flextube 400Pi SynScan GoTo Collapsible Dobsonian Telescope

Combining space-saving design and a simple floor base with sophisticated gear for seeking out celestial treasures, the Flextube 400Pi SynScan GoTo Collapsible Dobsonian Telescope from Sky-Watcher offers memorable experiences in the study of the night sky. Its large 16" aperture, 1800mm focal length, and f/4.4 focal ratio deliver dazzling views of planets, the moon, nebulae, galaxies, and more. The built-in Wi-Fi allows for SynScan control through the proprietary app, which makes it easy to search out specific objects or tour the cosmos.

Optical Tube Assembly

• 16" (406mm) aperture can resolve dim deep-space objects, like wispy nebulae and galaxies
• Fast f/4.4 focal ratio ensures a wide field of view & maximum light throughput
• For astrophotography, the fast focal ratio will result in shorter exposure times versus " slower" OTAs while achieving similar results
• Long 1800mm focal length helps to produce the fast focal ratio and magnification range
• Collapsible truss system eliminates the need to disassemble the telescope after use and saves space during transport and storage, measures 42.5" when trusses are retracted and extends to 66.5" when set up
• Borosilicate parabolic primary mirror with aluminum coatings that bring the reflectivity to 94%
• Resolution: 0.29 arcsec (Dawes Limit), 0.34 arcsec (Rayleigh Limit)
• 102mm diameter secondary mirror Obstruction: 25% by diameter, 6% by area
• 74" eyepiece height when aimed directly overhead at the zenith

SynScan Control

• Built-in Wi-Fi module allows the use of the SynScan smartphone app to control the base, available for Apple and Android devices
• User-friendly menu system
• Up to 5 arcmin GoTo pointing accuracy
• Brightest-Star and Two-Star assisted alignment procedures
• Sidereal, lunar, solar tracking rates
• 1x, 2x, 8x, 16x, 32x, 200x, 400x, 600x, 800x, 1000x slew speeds

Database Details:

• 42,900 objects including planets, nebulae, star clusters, and galaxies
• Tour of the night sky based on location, date, and time
• 25 user-defined objects
• Includes the complete Messier, NGC, and IC catalogs and partial SAO catalog

Focuser

• Crayford-style is much more precise than the traditional rack-and-pinion
• Tension control system eliminates gears, resulting in zero backlash for tack-sharp focus on dim objects, or objects like binary stars which are close together
• 2" diameter holder allows the use of larger eyepieces and imaging systems that provide a wide field of view and eye relief for more comfortable viewing of dim and small deep-sky objects

Base Details

• Dual axis DC servo motors with encoders
• Dual encoder design keeps track of where the scope is being moved, allowing you to move it manually without the need for re-alignment
• Tension control handle allows you to add or reduce tension, increasing or decreasing the friction between the optical tube and the sideboards
• Included 10-15 VDC 1A power supply
• Dimensions: 36 x 24"

Included Accessories

Eyepieces:

• 1.25" diameter nosepiece accepts most standard filters
• 25mm focal length eyepiece produces a low 72x magnification for wide-field observations, alignment, and viewing lunar surface details
• 10mm focal length eyepiece yields a high 180x power to make detailed observations of specific portions of the sky or for planetary viewing

Reducer Adapter:

• 2-to-1.25" reducer allows the use of more commonly sized eyepieces and accessories

Finder:

• Low 9x power produces a wide field of view for accurate alignment
• 50mm objective allows you to see dimmer stars for more options during 2-star alignment
• Mounting bracket included
