A Look at the Astrophotography-Oriented Canon EOS Ra

The Canon EOS Ra is a specialized camera, but one that is quite intriguing for anyone interested in astrophotography. This great video takes a first look at it to see if it is right for you.

Coming to you from Astro Backyard, this great video takes a look at working with the new Canon EOS Ra astrophotography camera. What makes the camera especially interesting is that Canon's RF lenses have been absolutely spectacular, and that in combination with the specialized sensor could end up being a real boon for astrophotographers. Furthermore, the Ra is the first specialized astrophotography from Canon in seven years (preceded by the 60Da and 20Da) and the first to sport a full frame sensor along with almost a decade's worth of sensor technology advancements. The astrophotography capabilities come from an optical infrared cut filter placed in front of the sensor. This allows for four times improved transmission that enables the capture of galaxies and nebulae emitting light at the Hydrogren-alpha wavelength (656.28 nm). Furthermore, the camera allows for 30x magnification using both the rear LCD and the EVF, making manually focusing on stars much easier. It is quite the interesting camera; check out the video above for the full rundown.

I love the look Ashley gives him, she knows she is stuck there for awhile.

I guess we have to thank Ashley first for being patient with him. The last photograph was outstanding. If I get into astrophotography I might look up this camera. Thank you for the short and sweet video!

This youtube channel is one of my favorite for astrophotography...
and the results with this EOS Ra look very cool !

That seemed more like a shill for the 85mm than the Ra. ;-)

If you're gonna shoot with an astro camera, money is much better spent on a dedicated astro camera. If you're gonna go the DSLR or mirrorless route, then it's much cheaper to simply mod any number of cameras out there. The Nikon D5300 is a popular APS-C frame camera to mod (the smaller sensors making better use of most scopes FOV).

BTW, if you're gonna use a camera lens to shoot, use a UV filter, and instead of stopping down, use filter step-down rings in front of the lens. The gives you at or near a desired aperture without inducing diffraction spikes. The UV filter tames UV radiation coming from various astro sources. This is especially handy with older lenses that many people use for po' man's astrophotography. This works wide or tele.
