Re: Canon EOS Ra Sensor Measurements at PhotonsToPhotos

Thanks for running the numbers. Is the change in PDR/read noise strictly due to the way the red channel is operating or is there something else like binned sensor/CPUs?  The 60Da has the same firmware as the 60D, but the Ra has specific firmware.

The 60D and 60Da didn't have the same degree of difference in PDR or read noise.

ASTRO PERSPECTIVE
It's interesting because a lot of dedicated astrophotographers have found the Ra to be really impressive in use for a simple one-shot camera.

Richard Wright from Software Bisque was gushing over it in this video. Software Bisque makes one of the flagship "tripod heads" (mounts) for astrophotography

These are the types of mounts used by universities and other researchers to do things like exoplanet discovery like KELT and MEarth.

DAYLIGHT PERSPECTIVE
Both the 60Da and EOS Ra are less aggressive with their Ha filters than aftermarket modification. Daylight performance has increased IR leakage (like the old Leica M8) but it's somewhat fixable if your standard for quality is lowered.
