Canon Mirrorless APS-C Sensor Astrophotography Modification

  • $229.00
    Unit price per 


 

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:


1A. UV/IR blocking filter removal with LPF (Enhanced Spectrum)

     

    This conversion preserves the Low Pass Anti-Aliasing filter with self-cleaning function. The spectral sensitivity of the camera sensor will be Enhanced Spectrum (For a complete description of a ES conversion please read options 2A or 2B), allowing Hydrogen Alpha and Sulfur II wavelength emissions pass but still blocking UV/IR light. The main purpose of the LPF is eliminate moire effect but at the cost of sacrificing sharpness slightly introducing a little blur effect and it also reduces color noise. With the Low Pass Filter only preserved, in most cases the sensor distance to the lens bayonet can be adjusted accordinly to match the diffraction index differential to reach perfect focus to infinity with lenses. The sensor repositioning distance range can be confirmed once the camera is disassembled. Perfect focus of subjects closer than infinity with lenses can still be achieved, but for focus to infinity with lenses capability option 2A is guaranteed for all models and options 2B and 3 are guaranteed for most models. Telescopes will always reach focus to infinity without any problem.


    1B. UV/IR blocking filter removal without LPF (Full Spectrum)

     

    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). With the bare sensor modification, the sensor distance to the lens bayonet will be adjusted to have perfect focus to infinity with lenses when a Clip-in body filter like the Astronomik L-2 UV/IR blocking or CLS is attached to the camera body. When combined with a Clip-in filter like the Astronomik L-2 UV/IR blocking or the Clip-in MC Clear glass, the total price of this conversion is less than the internal filters modifications.


    2A. Enhanced Spectrum conversion with Baader or AstroGear Luminance Filter and LPF

     

    For this conversion, the Baader or AstroGear UV/IR Cut Anti-Reflective filter (Depending on filter availability) with enhanced H-alpha and Sulfur II sensitivity is installed preserving the Low Pass Anti-Aliasing Filter with self-cleaning function. This is the most convenient modification for wide field astrophotography with lenses because focus to infinity is guaranteed in all Canon Mirrorless APS-C models. The sensor filters configuration of this modification is the same of the Canon EOS 60Da and Canon EOS Ra. This conversion does not require an additional or external UV/IR Cut filter. 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.


    2B. Enhanced Spectrum Conversion with Baader or AstroGear Luminance Filter only

     

    On this conversion both Low Pass Anti-Aliasing filter with self-cleaning function and the UV/IR blocking bluish filter are removed and replaced by the Baader or AstroGear UV/IR Cut Anti-Reflective filter (depending on filter availability or camera model) with enhanced H-alpha and Sulfur II sensitivity. This conversion does not require an additional or external UV/IR Cut filter. Perfect focus to infinity with lenses capability is guaranteed for most Mirrorless APS-C cameras models. 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. 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.

    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 only

     

    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.

    This is the most versatile conversion, is suitable for UV/IR Photography, Regular Photography and Astrophotography. The camera will capture the entire visible spectrum including Hydrogen Alpha and Sulfur II emissions plus Ultraviolet and Infrared light. Perfect focus to infinity with lenses capability is guaranteed for most Mirrorless APS-C cameras models. Both Low Pass Filter with self-cleaning feature and the original UV/IR blocking bluish filter are replaced by the Astronomik Multicoated Anti-reflective Clear filter. With the Low Pass Anti-Aliasing Filter removed, the Camera Sensor performs at native maximum sharpness.

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

    For daylight or regular photography an additional Original White Balance filter is required. The Astronomik OWB Clip-in filter can be used with all lenses.
