This is a 114mm diameter portable telescope that I designed. It is an interesting project, you can take your small but powerful travel telescope anywhere in your backpack.
You will need 6 3/8 inch aluminum tubes. The length of these tubes depends on the focal length of your telescope, but make sure the focal length is not greater than 550, because you will need to add counterweights to the base of the primary mirror.
Additionally, it is important to print with at least 50% infill to obtain the necessary firmness.
This small but powerful telescope can be assembled and transported in a box measuring approximately 25x25x5 cm. I used a wooden one that I had at home.
In summary you will need:
- 6 tubes of 3/8 inch cut to size according to your focal length
- A box of approximately 25x25x5 cm to organize the telescope
- some screws and their nuts (I forgot the measurement, but you can measure using your trusty slicer)
- A set of mirrors for telescopes with a diameter of 114mm and a maximum focal length of 550mm and a secondary mirror of 25.
IMPORTANT: the base of the secondary mirror must have an internal nut (again I forgot the measurement hehe) you must configure your trusty slicer to add a stop and insert the nut.
oh finally... you may have to sand some pieces to make them fit, I used an ender 3 v3 se to print all the pieces, it may be that it was not set up correctly. In any case, experiment with this little guy, I will accept and try to correct any imperfections. THANK YOU!
