Overview

The Sky-Watcher FlexTube 200P gives you a genuine 8-inch aperture at f/6, which puts real deep-sky observing within reach. With 200mm of light-gathering power, you can resolve globular clusters like M13 into individual stars, pick out dust lanes in nearby galaxies, and split tight double stars with ease. The collapsible strut design is the defining feature here: three retractable steel struts let you reduce the tube length significantly for transport and storage, while reportedly maintaining collimation between sessions, a real advantage over hauling a full-length tube around.

The dual-speed Crayford focuser handles fine focus well, and the included 8x50 finder scope is a genuine asset for star-hopping, not an afterthought. The two included eyepieces (25mm and 10mm) give you 48x and 120x to start, which covers most common targets reasonably well. Worth noting: at 40 pounds total, this is manageable but not light.

The Dobsonian mount requires manual tracking, so planetary viewing at high magnification means nudging the scope frequently. The 3.9 Amazon rating from 96 reviews suggests some buyers have encountered quality control variability, so inspect your unit carefully on arrival.

Key Features

  • 200mm aperture gathers enough light to show detail in galaxies, nebulae, and globular clusters under reasonably dark skies
  • Collapsible strut design reduces tube length for car transport and apartment storage without requiring full recollimation each session
  • Dual-speed Crayford focuser gives precise control at higher magnifications where sloppy focusing costs you detail
  • Included 8x50 right-angle finder scope is large enough for genuinely useful star-hopping navigation
  • Teflon azimuth bearings and tension-control handles allow smooth, controlled manual tracking without counterweights
  • Fully multi-coated mirrors with 94% reflectivity maximize image brightness, particularly valuable on faint deep-sky objects
  • At $850, this delivers aperture per dollar that refractors and Schmidt-Cassegrains at this price point cannot match

Perfect for a beginner to Amateur

I have never owned or operated a telescope before but I began looking for a beginner scope for over a year now. Upon several reviews and forum ratings, I originally went with the Celestron 127EQ (Big Mistake) So I immediately returned it. Not only was the mount hard to maneuver but darn near impossi...

Great Dob scope for star hopping

I purchased this after getting a cheap scope with an unstable tripod. Reading the reviews the Dobsonian mounts were easy to use and great for the backyard. The telescope arrived in two boxes like described and I had already watched YouTube videos on assembling. It really was easy and anyone who has ...

1-star AF

If you’re looking for tons of practice collimating telescopes but none of the reward of a clear image of the night sky, this is the telescope for you. I’ve owned this scope for about a month and a half now and I haven’t gotten one single clear image out of it. I’ve tried everything: collimating it c...
