47]This sunny morning 8-8:30 (UTC+2==16-16:30 AEST) in the Netherlands, Sun 12º above horizon, crystal clear. I grabbed my 25cm Dob and looked up Jupiter and I really saw Io, Ganymede and Europe. I couldn't find Callisto it was a lot further away from Jupiter. Particularly @230x (Nagler 13T6 + 2.5x Powermate) they were easy to see. Without Powermate (93x) it was slightly harder to see.
Then I pointed to the Pleiades (N 13T6 without Powermate, 93x) and saw Alcyone easily. Then I found Atlas, Pleione and Maya.
I found them by using altazimuth setting circles and a coordinates app.
