Any amateur astrophotographer with experience using DSLR cameras will tell you that the amount of noise in your image will increase as you bump up the ISO. This is extremely useful for astrophotographers, as we regularly point the camera in all sorts of awkward angles. Because the EOS Ra is a mirrorless camera system, the electronic eye-level viewfinder is able to provide the magnification feature. Traditionally, this would be at a magnification of 10X, but Canon has upped the ante. The best way to focus your camera lens or telescope with a DSLR or mirrorless camera attached is to zoom-in on a bright star and magnify it. This modification allows much higher transmission of deep red infrared rays emitted by nebulae, without requiring any other specialized optics or accessories. The infrared-cutting filter positioned immediately in front of the CMOS imaging sensor is modified to permit approximately 4x as much transmission of hydrogen-alpha rays at the nm wavelength, vs. For the same reason I invested in the Canon 60Da, I like the idea of Canon handling the astro-modification and not voiding the warranty with a third-party service. In my tests with the 60Da, the colors are slightly off and create unappealing daytime images without serious adjustments in post. The This camera has some impressive specs for photography and videography including shooting 4K at 30p with Canon Log. Not only is it a different style of camera mechanically, but it also accepts Canon RF Lenses. This camera is aimed at landscape astrophotography enthusiasts such as wide-angle Milky Way photographyand deep-sky imagers using an equatorial telescope mount.

This is called modifying your camera for astrophotography and is offered professional from several vendors. Historically, amateur astrophotographers that wanted to collect the powerful deep reds found in many emission nebulae with their generic DSLR cameras had to remove the stock internal IR cut filter. Thankfully, some new and exciting example images have already surfaced from those that were granted early access to this camera body, and from Canon themselves.Īs many of you know, some of the absolute best deep-sky nebula in the night emit a strong red signal in the nm wavelength. Here is a short video showing one of my first experiences with this camera and an RF-mount lens. For a niche hobby like astrophotography, the Canon EOS Ra has sure attracted a lot of attention from the photography world. This is a Increased sensitivity to the nm h-alpha emission line, and a 30X live view focus mode.
