I looked at your Exif details on this one. You'll have to explain f/0 to me. Is the camera body attached directly to the telescope? I'm guessing that would explain it.

Yes, that's correct. An adapter known as a "T-Ring" turns the scope into, essentially, a fixed FL lens. The camera, however, can't for whatever reason correctly identify the scope's focal properties.
For the record : The C6 is an f/10 out of the box. There are reducers available, the most common of which take it down to an f/6.3
This picture is is a shot of Betelgeuse taken through the Bahtinov mask to evaluate focus.
