Canon EOS Ra at full resolution of 6720 x 4480?

I'm using BYE with a Canon EOS Ra attached to a 4" refractor.

In Planetary mode, what do I need do set to capture images at the full resolution of the sensor (i.e.: 6720 x 4480)?

Currently when I save images with the 5X button selected, they are saved at 1344 x 896.

Thanks!

With Canon cameras 5X zoom is a full resolution crop of the selected portion of the image. 

You cannot get a full image at full resolution with LiveView (Frame & Focus, Planetary, Drift Align) because of the design of the camera. Planetary mode uses LiveView and unzoomed LiveView images are downsampled to fit on the LCD display. These downsampled images are sent to BYE. 5X zoom is 20% of the width and 20% of the height of the full image, at full resolution, which by design fills the LCD display. This is the full resolution of the sensor where there is a 1:1 ratio between sensor pixels and image pixels.

Got it, that makes perfect sense now. 1344 pixels is 20% of 6720.

Thanks so much,
