Canon EOS Ra is the first astrophotography camera that will be so easily accessible to amateurs. Based on the EOS R construction and available in all stores, it will become an interesting proposition for those who love the night sky.
Canon EOS Ra is not a completely new model, but a very interesting extension of the already known EOS R mirrorless camera. The camera has practically the same specification as this well-known model, but extended with a filter providing four times better transmission in the H-alpha (Hα) radiation range in relation to EOS R. This will allow you to successfully use it in night sky photography.
The most important features
- Filter providing four times better transmission in the H-alpha (Hα) range; compared to the EOS R.
- 30x magnification in live view mode.
- Focus peaking – a function supporting manual focusing.
- 35mm full frame CMOS sensor with approximately 30.3 million effective pixels and the latest DIGIC 8 processor.
- Faster communication of the lens with the camera body thanks to Canon RF mount.
- Lightweight construction without a mechanical mirror; reduction of internal micro-shocks when connecting a telescope.
- Work in very limited lighting conditions.
- Tiltable touch screen.
- 4K video recording with 10-bit output via HDMI.
Canon EOS Ra for fans of the night sky
The EOS Ra is equipped with the same functions as the full-frame EOS R mirrorless presented in September 2018 . Thanks to this, the new model has, among others the fastest autofocus in the world, the ability to focus in extremely low light conditions from -6EV, a 35mm full-frame CMOS sensor with approximately 30.3 million effective pixels and a DIGIC 8 image processor.EOS Ra is additionally equipped with in a new filter cutting off infrared radiation (IR filter) , which allows the matrix to reach four times the number of "H-alpha" spectral lines (radiation with a wavelength of about 656 nm), compared to the model EOS R. The IR filter allows you to capture a clear , the red color of the emission nebulae – interstellar gas clouds composed mainly of hydrogen and helium – which is impossible with a traditional camera in which UV / IR filters block a significant part of the radiation, giving the nebulae their characteristic color.
Sharp and clear photos
The mirrorless construction of the camera helps to provide an image without moving, which is necessary for photography of the night sky. No mirror, 5-axis matrix stabilization and the ability to remotely control the smartphone – all this is to guarantee sharp and clear photos taken with a long shutter speed.The camera also records 4K videos , including time-lapse sequences. This in turn allows you to record interesting timelaps of stars moving in the night sky. The full-frame matrix, on the other hand, ensures high camera sensitivity, i.e. grain-less photos even at higher ISO values. The body design allows for easy attachment of the camera to the telescope.
Price and availability
The Canon EOS Ra is expected to be available in December this year. It was valued at $ 2,500 , which is $ 700 more than the currently available "standard" EOS R.
