DeadJohn, when Q appeared, I first thinking of using it to astrophoto: good image, small sensor, lot of pixels. Wish Pentax give us some flexibility, e.g. 100% crop movie. PKtether can do this?
I've tried full hd on Sun with k5iis, thinking that using a longer focal length will surpass the binning he did, but the result was not good, perhaps seeing was bad or just the first try was unlucky. One frame produces interesting and unexpected good results. Also filming the moon and stacking didn't do much, I got (far) better result from a single frame. I believe the camera introduces some sort of soften in addition to the binning itself.
Single frame, 100% crop, 1500mm f/18:
The whole image (minor crop, resize):
