Spectrometer for Astronomy

thingiverse

Inspired in diverse DIY spectrometer based on DVD. The main tube has a size of 1 1/4 for telescopes. I paint mine with a black mate spray to avoid reflexes. The slit is provided in various sizes because the real size will depend on the 3D printed used. A slit of 4mm is also provided to glue a paper slit or whatever. A PDF is provided to cut the DVD into the correct shape. The DVD (or CD) should be previously pealed off with duct tape or equivalent.
