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
