constellation-projection device,Optical system
It was carried out to create of constellation-projection device which can project constellation as seen from our Miyagi region with easy “Students’-made”.
We considered about the accuracies of stellar locations and shaped stellar images. At the stage of design, we calculated the pinhole sizes less than φ2.5 and the height of light source from base is 19.1mm.
We discussed about the raising accuracies with keeping low cost.
