Sky-Watcher Flextube 250P SynScan 10" f/4.7 Dobsonian GoTo AZ Telescope
Key Features
  • Large 10" f/4.7 Aperture
  • 1200mm Focal Length
  • Highly Reflective Borosilicate Mirror
  • Space-Saving Collapsible Tube Design
Sporting the large light bucket users have come to expect from a Dob, the Sky-Watcher Flextube 250P SynScan 10" f/4.7 Dobsonian GoTo AZ Telescope gives users great performance at a reasonable price. Its large parabolic Borosilicate primary mirror is treated with an aluminum coating that brings its reflectivity to over 94%, with a secondary mirror obstruction of just 6% by area. Unlike traditional Dobsonians that tend to be bulky and unwieldy, the Flextube's patented truss design allows it to retract to just 33" for easier transport and storage and extends to 44" for observation.

Optical Tube Assembly

  • 10" (257mm) aperture is able to resolve dim deep-space objects like wispy nebulae and galaxies
  • Fast f/4.7 focal ratio ensures a wide field of view & maximum light throughput
  • For astrophotography, the fast focal ratio will result in shorter exposure times than "slower" OTAs while achieving similar results
  • Long 1200mm 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—measuring just 33" when trusses are retracted and 44" when set up
  • Borosilicate parabolic primary mirror with aluminum coatings that bring the reflectivity to 94%
  • Resolution: 0.46 arcsec (Dawes Limit), 0.55 arcsec (Rayleigh Limit)
  • 64mm diameter secondary mirror; Obstruction: 25% by diameter, 6% by area
  • 49" 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—app is available for Apple and Android devices
  • Wired hand controller, powered by the mount, provides all the same functionalities as the app
  • 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 objects that are dim or close together, like binary stars
  • 2" diameter holder allows the use of larger eyepieces and imaging systems that provide a wide field of view and long eye relief to make viewing dim and small deep-sky objects more comfortable

Base Details

  • Dual-axis DC servo motors with encoders
  • Dual encoder design keeps track of where the scope is being moved, allowing the telescope to be moved manually without the need for re-alignment-1,620,000 counts per revolution, main axis encoder: 11,748 counts per revolution
  • Tension Control Handle allows users to add or reduce tension, increasing or decreasing friction between the optical tube and sideboards
  • Included 10-15 VDC 1A power supply
  • Dimensions: 30 x 20"

Included Accessories

Eyepieces:
  • 1.25" diameter nosepiece accepts most standard filters
  • 25mm focal length eyepiece produces a low 48x magnification for wide-field observations, alignment, and viewing lunar surface details
  • 10mm focal length eyepiece yields a high 120x 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 the more common size eyepieces and accessories
Finder:
  • Low 9x power produces a wide field of view for accurate alignment
  • 50mm objective allows users to see dimmer stars for more options during 2-star alignment
  • Mounting bracket included

question

Can it be used for astrophotography?
Asked by: Anonymous
You can use this model for astrophotography, however, you will be limited to short exposure objects like the moon and planets, or maybe some brighter deep sky objects like the Orion Nebula. Anything else, you will need an equatorial mount to track (this type of telescope is an alt-az mount.

Is it a good telescope for viewing nebulas
Asked by: Heini
Yes, that one is very good. But the next one up would be better for Nebulas. And it seems to be more popular. It is 1500mm focal length vs 1200mm. Sky-Watcher 12" f/4.9 Collapsible GoTo Dobsonian Telescope BH #SK12GTCD • MFR #S11820 https://bhpho.to/3n5Iqua
