5X 1:1 Pixel Ratio

Question

I have a Canon 5D Mark II.

When I take a video of a planet, even with a 10mm eye projection in my camera adapter, the video of the planet is very very tiny in the frames.

When you speak of the  5X that supposedly increases the pixels to 1:1,  does that mean my final outcome video frame will be of much greater magnification?

The "size" of a Planet is a factor of the Focal Length of the Scope and the Dimensions of the Imaging Sensor.  Even Jupiter is going to produce only a Small Image with Consumer Grade Optics and Cameras - unless you have a 4x/5x Barlow on a 14"-16" SCT - covering a few hundred pixels at most.  If using the DSLR's built-in Video Modes which utilize the entire breadth of the Canon 5D Mark II 21MP Sensor to produce a 1080p Video, it will be even smaller by 2.7x.

Instead, BYE uses a 1:1 Crop of the LiveView feed (which is only about 1000 pixels wide) centered on your target to capture the highest possible resolution of whatever Image Size your Optics is able to produce.

Beyond that, the use of Planetary Video Capture routines in Post-Processing Software will use that data to produce the Sharpest and Most-Detailed Image possible.
