A Mirrorless Camera modification for Astrophotography consist of the Hydrogen Alpha wavelength bandpass transmission increase at 656nm emission line and the Sulfur II wavelenght transmission increase at both 671.7nm and 673nm emission lines. The original UV/IR Blocking filter present on stock DSLR Cameras only allows over 25% transmission of H-alpha emission line and over 15% of Sulfur II emission lines. An Astro-Converted 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.

CONVERSION TYPES:

 

 

1. UV/IR blocking bluish filter removal only (Full Spetrum)

 

This is the most unexpensive conversion, most recommended to save money. Having the sensor bare or "naked" the camera will become Full Spectrum (For a complete description of a FS conversion please read option 3). Perfect focus of subjects closer than infinity with lenses can still be achieved but the camera will not reach focus to infinity. Telescopes will reach focus to infinity without problem.

 

 

2. Enhanced Spectrum Conversion with AstroGear Luminance Filter

 

On this conversion the UV/IR blocking bluish filter is removed and replaced by the AstroGear UV/IR Cut Anti-Reflective filter with enhanced H-alpha and Sulfur II sensitivity. This conversion does not require an additional or external UV/IR Cut filter. The sensor is adjusted to have perfect focus to infinity with lenses. 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 white balance presets without the need of additional original white balance filters.

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.

 


3. Full Spectrum conversion with Astronomik Anti-Reflective Clear Glass

 

The Full Spectrum modification is the best conversion for planetary astrophotography because the possibility of using infrared isolating filters like the Astronomik ProPlanet 742 IR-pass and 807 IR-pass . The infrared wavelength is significantly less susceptible to poor seeing (atmospheric turbulences) and consequently the resulting images are considerably sharper. Expert planetary imagers process planets photos with single line infrared filters as a luminance channel. The Astronomik MC Clear glass is installed in front of the sensor replacing the stock UV/IR Blocking bluish filter.

This is the most versatile conversion, is suitable for UV/IR Photography, Regular Photography and Astrophotography. This modification has the same Full Spectrum wavelength sensitivity specifications as the UV/IR Blocking filter removal only modification. The sensor is calibrated for perfect focus to infinity with lenses. 

Out of focus Infrared: An additional UV/IR cut filter is required to capture the pictures in visible light. This filter is a must when imaging with telescopes using refractive elements (refractors, catadioptrics, reducers/flatteners, coma correctors, etc.) If light frames are captured without an UV/IR blocking filter you will get bloated stars, because UV and IR light rays focus at different distance from the visible light focal plane.

A luminance filter, or any narrowband filter will cut off Ultraviolet and Infrared Wavelengths.

For daylight or regular photography an additional Original White Balance filter is required.
