Nikon D5100 Astro Modified (Body Only)-Used
- Product Code: ND5100DS
DreamSky BCF Astro-Modified
A DSLR or Mirrorless Camera modification for Astrophotography consist of the Hydrogen Alpha wavelength bandpass transmission increase at 656nm emission line and the Sulfur II wavelength transmission increase at both 671.7nm and 673nm emission lines. The original UV/IR Blocking filter present on stock DSLR or Mirrorless Cameras only allows over 25% transmission of H-alpha emission line and over 15% of Sulfur II 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. The hydrogen element is present in the entire universe, and many emission nebulae visible on the night sky emanate hydrogen alpha emissions.
