Did some test photos of Jupiter and Moon at prime focus.
Moon (approx 4 days old) 0.04 (1/25) quite good (iso 400).
Jupiter 0.05" (1/20) iso 400.
Jupiter and Moons (Planet a bit overexposed) 0.1" (1/10) iso 400.
I usually write a blog post about once a week. The latest post can be viewed here: Too Many Road Cones: I think it is clear, there are too many road cones! (posted 2025-07-18 at 16:55:03). I do podcasts too!. You can listen to my latest podcast, here: OJB's Podcast 2025-06-28 An Empathy Deficit: They end up reducing the total empathy in the world..
