Testing, testing, testing

We took a closer look at the design of the telescope and divided it into several work packages. The mechanics of the Dobson mount should be easy to create. The optical parts are of major interest as they might be tricky to create.

So we need to define components and test them. Particularly important parts are, in our opinion:

  1. The Focuser: Is it mechanically stable and yet precise enough to hold an eyepiece securely and hold it in the optical path without tilting? If not, we might need to buy a focuser.
  2. The Dobson hat: Is it stable enough and how could we mount the spider? If stability is lacking, it would have to decide if we can create our own, better design or if we need to cancel the project.
  3. The mirror cell: How is the mirror fixed and, above all, adjusted?
  4. The mirror box: How is the mirror box assembled and the mirror cell anchored in the box?
  5. How are all of these components assembled with aluminum bars to create an optical system that is adjustable so we can expect a decent imaging performance later on?

We have to print and test a lot to understand how everything can be put together. Let's get down to work.

Since Ansi lives in Berlin and I live in Friolzheim, we have to work in a distributed manner and still act in a coordinated way. We split up our tasks like this:
I do the first test prints and test how the parts are assembled. It is also of great help that I own a 8" travel dobsonian where I can check and potentially develop ideas.
Ansi has the professional software and hardware on site, so he prints the final parts for assembly in high quality.

The first test prints are already running and so far everything looks very positive.
