Things are changing in the mirrorless universe. The Canon EOS R5 and EOS R6 are…
If you never heard about the Canon EOS Ra, it’s a modified EOS R camera and Canon’s full frame mirrorless offering for astrophotography enthusiasts.
The EOS Ra was built off the EOS R system combining new features, such as four times greater transmittance of hydrogen-alpha Hα rays (656.3 nm wavelength) through an infrared cutoff filter, which helps capturing high-precision images of the deep-red wavelengths emitted by nebulae in vivid color, without any special camera alterations. On board is also a 30x live view mode for highly precise manual focusing.
The video below by CanonUSA on Youtube features an interview with astrophotographer Tony Hallas about astrophotography itself and his experience with the EOS Ra.
More Canon EOS Ra reviews and information are listed here.
Canon EOS Ra key features and description:
- Optimized for Astrophotography
- IR-Cut Filter Passes H-Alpha Wavelength
- 30x Magnification for Focus in Live View
- 30.3MP Full-Frame CMOS Sensor
Developed specifically for those looking to photograph the night sky, the Canon EOS Ra is a modified version of the original EOS R that incorporates an optical IR cut filter in front of the sensor for photographing distant nebulae and other astronomical phenomena with utmost clarity. By updating the EOS R’s design with a dedicated filter, the EOS Ra provides approximately 4x improved transmission and sensitivity to H-alpha (656.28nm) wavelengths for depicting nebulae and other subjects without unwanted infrared contamination for greater color neutrality. Additionally, a 30x live view magnification setting has also been added for improved focusing precision on distant subjects when working with either the EVF or rear LCD. Beyond these couple distinctions, the EOS Ra and EOS R feature the same set of core features to produce high resolution, well-detailed imagery.
