Abstract:
We built a demonstrative Littrow Spectroheliograph with available optical components to learn the basics of spectrography and applying the principles to image the Sun on narrow band spectral lines, obtaining 2D images with dedicated spectroheliograph reconstruction software (SHG v.4.3). We present the first images in different wavelengths and the capabilities of the instrument.
