I deceided to make a 30cm dobsonian when I was 18y old. I bought the optics by Orion Optics UK and made a telescope using the book "the dobsonian telescope from kriege & berry".

An article about the construction of this scope was published in the belgian magazine "distant targets" in 2004.

Here are some pics of the components of this scope:

This is the mirrorcell. Remarks it's 9points support and open design and fan to let the mirror cool down fast.

The secondary cage.

The pole clambs were somewhat though. I deceided not to use the pole clambs kriege suggests in his book but I made a U-profile and clambs to attach the poles to the mirrorbox. This works great!

The bearings
