The reflection looks like a narrow slit. The sewing needle is at the focal plane of the 70 mm refractor. The refractor is the collimation lens. The light travels up the refractor back wards and is transformed into a parallel beam after the 70 mm objective. The parallel beam goes through the plastic 500 lines/mm grating that is mounted on the Sony Handycam 37 mm filter threads. The grating disperses the parallel beam into a spectrum. The Sony Handycam records the spectrum and it has a HDMI output for real time viewing of the spectrum. Spectroscopy
