How to do get stars spectrum for $5 cheap. Simples steps of how to get stars spectrums:

  • Get transparent plastic for lazer printing (pics/paper_lomond) samples.
  • Get a lazer printer with at least 600 dpi
  • Generate desired grid using dif_generator.lua,

usage: dif_generator.lua lines_per_mm dpi > grid.svg

  • Print that grid (pics/paper_printed)
  • Make a mask for your telescope((pics/paper_usage)
  • Have fun pics (pics/spectrum_aldebaran)

I spent $5 for this paper set only.
