My home made truss tube dobsonian. Click here to see the build process.


Well there it is. I took an age to build but the deep sky views are astounding. Unfortunately collimation doesn’t stick so I don’t really use it for solar system work – will need to make some modifications before it’s any good for that stuff. For low powered viewing it’s a great light bucket.

Advantages of the SCT

  • Cost – not as expensive as purchasing a truss tube scope
  • Massive Aperture for the amount of space it uses up
  • Can be taken apart in 5 minute take down for transport
  • No power required


  • Heavy Heavy Heavy!!!
  • Needs to be realigned every time I setup (I need to improve the tube holders – top and bottom)
  • Long cool down time
