I had two years of failures at trying to see Amalthea, and eventually the key was using my Denk Binoviewer with 10mm ZAO II’s at 619x. So I use all sorts of mono and bino eyepiece combinations depending on the situation.
I’ve written of this a bit on Cloudy Nights, but no one there seems aware of anyone observing the really faint moons. As you say, not a lot of people doing it for what ever reason. But I find it fascinating and challenging. It’s possible no one has ever visually seen the group of Jovian moons I observed this week. That’s why I thought I would pose the question here given the knowledge of some of the members.
