On Canon launches EOS 60Da DSLR for astrophotography article (228 comments in total)

"This produces a 20-percent higher transmittance of Hydrogen Alpha line, or Hα wavelength, allowing astronomers to capture crisp, clear images of reddish, diffuse nebula" only makes sense if one assumes that "20-percent" is a misprint for "200-percent". Do others agree with me, or am I missing something?
