The Canon EOS Ra is a mirrorless camera that has been customized specifically for use in astronomy and is based on the EOS R. The EOS Ra has a transmittance of hydrogen-alpha (H) light with a wavelength of 656.3 nm that is four times higher than that of its predecessor, making it possible to show nebulae and other topics without the presence of undesired infrared pollution and achieving improved color neutrality.

It comes with a powerful DIGIC 8 Image Processor and a 30.3 megapixel full-frame CMOS sensor, both of which work together to offer exceptional image quality with very little noise. The Dual Pixel CMOS AF phase-detection technology with 5655 customizable AF points allows for the acquisition of focus to be done both swiftly and precisely.

The OLED electronic viewfinder (EVF) of the EOS Ra has 3.69 million dots, and the tilting LCD touchscreen is 3.15 inches. In addition, the 30x magnification setting has been included for users so that they may make incredibly exact changes to the manual focus.

UHD video in 4K (3840 by 2160 at 30 frames per second) may be recorded at up to 480Mbps on an EOS Ra. It is possible to export the uncompressed 4K 4:2:2 10-bit video using HDMI.

Other notable features include a continuous shooting rate of 8 frames per second, built-in Wi-Fi and Bluetooth, a customizable multi-function bar that enables users to make quick adjustments to camera settings, and dual pixel raw, which enables users to make fine adjustments to an image after it has been captured.
