vega spectra test IMG 2870
Raw diffraction spectrum of Vega using the SA100 imaged through an unmodified Canon 1100D and the Celestron 6SE at prime focus. The SA100 was approx 90mm from the sensor. Exposure time 1s at ISO 800. Spectrum looks a bit overexposed and there is light leakage across the sensor. However there is something there.
