On this page we provide information for the installation of our products, but also for the modification and tuning of a Newtonian telescope. Optimizing a telescope is NOT a "Rocket Science" and not only reserved for experts!
With some basic skills every hobby astronomer can do it ;-)
Here you will find some general instructions for tuning a Newtonian telescope on the example of a Skywacther Quattro 150. The procedure for other telescopes is similar, but may differs from the one shown here due to the slightly different design of other manufacturers. The individual steps do not all have to be followed! If you only want to replace the secondary spider, you can of course skip the other steps.
