That's a short exposure with no stacking. I used the Q, so I could get the most out of the lens without the sensor pitch being a factor. Aiming was not easy, nor was focusing.

Also looked at Jupiter with it. It makes a blob about as big across as the width of the rings, but I could not resolve any stripes or other features.

I tried Jupiter with the DFA* 85

Obviously way too small to be meaningful but at the same time what resolving power.  Saturn + rings was a smudge about that same size but it was just too small to see rings.
