Hello Everyone, I have a friend who has a Meade 90mm DS series refractor. It has a problem that I have never run across before. You can focus objects with it, however when you look at bright objects, such as Jupiter, the moons focus okay, the focus on Jupiter shows detail, except that Jupiter is surrounded with a bright round halo, any ideas on what is wrong? Thank in advance for any ideas.
