    Betelgeuse - focus
    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.
