I used a Clelestron telescope (2800mm) with a Canon mount adapter. Both Sun and moon are very bright so it works well. Not the same for stars etc. lI have also used the 100-400 II + 1.4xIII but its not nearly as close.

Telescopes are mirror designs, if I’m not mistaken? Those are supposed to be terrible lenses. How would you rate the detail you get using it?

What makes mirror telescopes good for astronomers but bad for photographers?
