About the Sky-Watcher Flextube 200P 8" Collapsible Dobsonian Telescope

If you love the superior light gathering capability of a Dobsonian telescope, but you want to be able to transport it easily then this offering from Sky-Watcher is tailored for you.

Many truss tube Dobsonians solve the portability problem by being designed to disassemble, which often results in a frustrating (and time-consuming) reassembly experience. Sky-Watcher have instead created a collapsible design. Just loosen three locking screws and bring the front and back cells together. Then lock them back down for transport. Preset indentations on the truss tubes allow you to easily extend the telescope again without losing collimation.

Teflon bearings allow movement so smooth that sweeping adjustments can be made with one finger. A tension clutch keeps the OTA firmly in position with the twist of a lever.

The 8" aperture and fast focal length of this telescope make it ideal for wide-field, deep-space observation of even the faintest nebulae and galaxies. Sky-Watcher's dedication to quality design and top-notch components result in an instrument that will delight even seasoned astronomers. The parabolic primary mirror and elliptical diagonal mirror are made of borosilicate glass which are finely polished to ensure high smooth surfaces and high-contrast images. On each mirror surface, aluminum is vacuum deposited and then over-coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied, resulting in 94% reflectivity and bold-bright images in the eyepiece.

Features

  • 203 mm (8 inch) Dobsonian-style Newtonian • 1200 mm focal length (f/5.9) ideal for deep-space visual observation
  • 2” single-speed Crayford-style focuser for smooth focusing • 1.25” adapter means that you can use both 2" and 1.25" eyepieces
  • Comes with everything you need to start viewing right away, including two 4-element Plössl eyepieces (25 mm and 10 mm) and an 8x50 RA erect-image finderscope
  • Solid rocker-mount with Teflon bearings and tension clutch for altitude
  • Teflon bearing for azimuth

Family enjoys it

I bought this as a telescope to take on camping trips with my family. It will need collimating nearly every use, but I knew that going in. Couldn't ask for more as far as a simple, portable set-up with decent aperture.

This shroud covers it all.

This shroud blocks out all of the light trespass in my area. It has two slots for the eyepiece and the finder scope. A must have item for this instrument.

Nicely emersive experience.

This lens has me looking into more 2" eyepieces from the same series. The views are amazing and Crystal clear. Literally room to stretch out the eyes.
Ring Nebula is so beautiful through this lens, truly breathtaking.

Fast, reliable, spot on customer service.

I have been in the market for an Ultralight 12" Dobsonian telescope. Ryan helped me with useful information on Explore Scientific telescope. What an amazing purchase. A high quality instrument and a dream come true for collimation. Great company, great scope.

Coming equipped with two decent eyepieces and an adapter is nice. Will upgrade to a 2" eyepiece one day, but not in the budget right now. Thanks to Ryan for help with ordering.

Easy

I'm enjoying the telescope very much. It's not too hard to assemble, although very slowly the first time.
