Build a Backyard Dobsonian Telescope

To put everything together, place the upper part of the mount with the altitude cutouts downwards, and put the azimuth bearing on top.

Now sink in the screw headsand you will get one right side and a left side board.

Both are universal telescopes, equally good both for planetary or deep sky observations. Your changes have been saved. Take one azimuth bearing board, and put the upper part of the mount on top, aligning the marks on the boards you draw earlier.

Now that we have a nice and stable mount, we can continue building the optical tube assembly OTA. It is very important that the hole is vertical relative to the board, since this is the axis of the azimuth bearing. Place the telescope within the holder and bolt the hold to the top of the base.

You will get everything you need from the local hardware store. An easier thing to do would be to buy a telescope tube directly from the hardware store; this will save you the trouble of constructing the tube yourself.


This page provides detailed plans and instructions how to build one. My finished inch Dobson telescope. Education How making is transforming learning. You will also be receiving the weekly Make: First we need to assemble the top part of the mount.

Take a old ruler, or a piece of wood, drill the same 8 mm hole at one end, put the M8x60 screw trough and drill a small hole 4 mm is fine at the outer edge of the board.

Besides, Los Angeles Sidewalk AstronomerPam Reid, did most of the work by writing and typing the procedures, as well as gathering the drawings–which, by the way, were done by Earl Jungians from photographs of John at work by Molly Lusignan.

Drill a hole in that spot and mount the spider in place. The mount works via friction, just little enough to easily move the telescope, but yet enough that the telescope remains pointed. It won an Innovative Telescppe Award for the adjustable cradle design.

Given any mirror measurements, PLOP will provide the ideal support layout and how much distortion to expect for any number of flotation points.

Building the mirror box is tricky, because the entire optical assembly mirror cell, mirror box, trusses, secondary cage must balance at the center of rotation of the arms.
