Summary

A simple telescope for an achromatic lens with a diameter of 31mm (1.25") and a focal length of 135mm. This is a fairly inexpensive standard lens and can be found in online shops for craft and science projects. Check our Website PrintedLabs.Uni-Bayreuth.de for an assembly tutorial.

The telescope is designed for use with C- or CS-mount cameras. To attach the camera, a C-mount to 1.25 inch adapter is required, which is standard for telescopes. A printable version can be found here:

The simple 2-axis camera mount, shown on the images can be found here:

PrintedLabs

Are you looking for exciting projects and creative experimentation in the STEM field? Then visit our website PrintedLabs.Uni-Bayreuth.de and take a look around. Whether you are a teacher, student or hobbyist and curious about physics and other STEM subjects - we offer a platform with a constantly growing selection of project ideas, DIY lab equipment from the 3D printer and matching software. Plus, of course, the necessary tutorials and assembly instructions.

To get started yourself, download our 3D models, software and instructions for free and experience for yourself how easy and inexpensive it is to realise your own experiments. With PrintedLabs, we not only want to awaken the joy of science and STEM subjects, but also promote analytical thinking, problem-solving skills and structured working methods. Our claim to ourselves is:

To make science and STEM subjects fun through self-built "lab equipment" and its application.
Developing analytical and creative thinking, problem-solving skills and learning structured working methods for setting up and carrying out scientific experiments.
The teaching of basic knowledge of data processing and the evaluation and interpretation of measurement data.
Good performance for detailed experimental results.
Compatibility of all components and associated software.
Simple and cost-effective assembly using standard tools and additional components.
Robust 3D-models in printing, production and handling.
High modularity to enable "free experimentation".

Notes:
Although an adhesive layer is not essential, I recommend rafts when printing all the components of the telescope at once. All components are designed and oriented in a way, that no supports are required. I will add a small tutorial video for the assembly soon.

ATTENTION!!!
If you want to use the printable sun filter frame for observing sunspots or just the sun, buy a professional, high-quality sun filter foil. Never use aluminium foil or similar.
Always handle the foil carefully and glue it firmly into the frame. Check it afterwards for holes or other damage. Always make sure that the sun filter frame is firmly attached to the telescope!
