Usage Information for EOS Ra (Disabled Low-pass Filter Effect)

The EOS Ra is a version of the EOS R designed for astrophotography. This camera has approximately four times the transmittance of hydrogen-alpha light (656 nm) as the EOS R. Photographs of subjects that refl ect a lot of infrared light will therefore appear redder than they actually are. Also, as it may not be possible to obtain an appropriate color balance or uneven colors may result, shooting normal subjects with this camera is not recommended.
