Canon DSLR APS-C Astrophotography Conversion

  Astrophotography or “H-Alpha” Conversion (Enhanced Spectrum: Visible + H-Alpha + Sulfur II)   On the Astrophotography camera conversion, the spectrum sensitivity is enhanced to increase Hydrogen Alpha wavelength bandpass transmission at the 656nm emission line and the Sulfur II wavelength transmission at both 671.7nm and 673nm emission lines. An Astro-Converted DSLR or Mirrorless Camera is about 4 and 6 times (H-alpha and Sulfur II respectively) more sensitive to the deep reddish nebulae structure tones. H-alpha objects/sections are also present in all the other galaxies besides the Milky Way. This conversion does not require an additional or external UV/IR Cut filter.   To read the Camera Conversions Types Guide please click here.      Description  Astrophotography Conversion options:   1.
