I thought I'd be able to get more detailed 300mm shots of the moon by using the OM-5 pixel shift. However, when the moon is the only thing in the frame, the camera will fail to combine the images in hand-held mode, even when shooting from a tripod with remote control. When something else truly stationary is in the frame as well, it will generate the high-res image and the stationary thing will be sharp, but distortions will be visible on the moon (especially at the edges) and it will not really be any sharper than when upscaling a regular 20MP shot. Same when using the 80MP tripod mode, it does generate the high-res but it contains distortions and isn't really sharp. It appears the moon is simply moving too fast at 300mm FL.
I thought that when the moon is the only non-uniform thing in the whole frame, the hand-held mode might be able to compensate for its slight movement, but apparently this mode relies on something else as reference points than merely the image content, and it notices that the shots do not line up as expected.
I guess it would be possible by mounting the camera on a tracking tripod that follows the moon's motion perfectly smoothly, but then it probably makes more sense to buy a decent telescope instead, or take a burst shot and feed those frames to some external super-resolving tool, exploiting the movement of the moon itself to act as the pixel shift.
