Canon full frame sensor dslr8/28/2023 ![]() ![]() Expert planetary imagers process planets photos with single line infrared filters as a luminance channel. The infrared wavelength is significantly less susceptible to poor seeing (atmospheric turbulences) and consequently the resulting images are considerably sharper. 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. (Ultraviolet + Visible + H-Alpha + Sulfur II + Infrared) Full Spectrum conversion with Astronomik Anti-Reflective Clear Glass only This chromatic aberration could be mitigated with post processing correction using computer software.ģ. 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. 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. 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. ![]() Perfect focus to infinity with lenses capability including autofocus with Pentaprism/Pentamirror mode is guaranteed for most Canon Full Frame cameras models. This conversion does not require an additional or external UV/IR Cut filter. 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 Optolong UV/IR Cut Anti-Reflective filter with enhanced H-alpha and Sulfur II sensitivity. Enhanced Spectrum Conversion with Optolong Luminance Filter only There is a layer of glass protecting the micro-lenses and bayer filters on top of the pixels.Ģ. When the stock UV/IR blocking filter is removed the surface of the sensor is not really naked. Without any glass above the sensor there are no internal reflections coming from a replacement filter. 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. Internal UV/IR blocking luminance filter and internal clear glass modifications (Options 2 and 3) are compatible with all Canon Full Frame Cameras. With the bare sensor modification, the sensor distance to the lens bayonet will be adjusted to reach focus to infinity with lenses and autofocus calibration in Pentaprism/Pentamirror mode with DSLR cameras when a Clip-in body filter like the Astronomik L-2 UV/IR blocking or CLS is attached to the camera body (Some Canon Full Frame DSLR Cameras are not compatible, please check compatibility list above). Having the sensor bare or "naked" the camera will become Full Spectrum (For a complete description of a FS conversion please read option 3). ![]() This is the most unexpensive conversion, most recommended to save money. (Full Spectrum: Ultraviolet + Visible + H-Alpha + Sulfur II + Infrared) UV/IR blocking filter removal without LPF Telescopes will always reach focus to infinity without any problem.ġB. Perfect focus of subjects closer than infinity will always be achieved in Live View Mode, but for focus to infinity with lenses capability including autofocus with Pentaprism/Pentamirror mode with DSLR cameras, options 2 and 3 are guaranteed for most models. The sensor repositioning distance range can be confirmed once the camera is disassembled. 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 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. The spectral sensitivity of the camera sensor will be Enhanced Spectrum (For a complete description of a ES conversion please read option 2), allowing Hydrogen Alpha and Sulfur II wavelength emissions pass but still blocking UV/IR light. This conversion preserves the Low Pass Anti-Aliasing filter with self-cleaning function. (Enhanced Spectrum: Visible + H-Alpha + Sulfur II) DSLR and Mirrorless Settings for AstrophotographyġA. ![]()
