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.

Optolong Luminance Filter Installation

 

On this conversion the UV/IR blocking bluish filter and the LPF (On models with Low Pass Filter) are removed and replaced by the non-detachable Optolong UV/IR Cut Anti-Reflective filter with enhanced H-alpha and Sulfur II transmission range. The Mirrorless camera will focus to infinity with lenses as before the conversion. With the Low Pass Anti-Aliasing Filter removed, the Camera Sensor performs at native maximum sharpness, which is also great for solar and planetary astrophotography. Astrophotography dedicated cooled cameras have the same sensor filter configuration of this conversion having an UV/IR blocking filter with the same transmission range without any low pass filter. 

 

Regular photography with an Enhanced Spectrum converted camera:

The camera can be used for daylight photography setting the custom white balance with a gray card shot under the specific light source for "In-Camera" white balance correction or with Adobe Camera Raw. To make the automatic white balance work as before the conversion, an Original White Balance (OWB) filter is required. 

 

Out of focus NIR: With the Enhanced Spectrum modification, depending on the lens, telescope or optical corrector used, some imagers might experience a little bit bloated stars due to the near infrared light slightly out of focus when a refractive optical system does not have at least one ED (Extra-Low Dispersion glass) element. This chromatic aberration could be mitigated with post processing correction using computer software.
