Too much chromatic aberration. What did I expect? To be more descriptive ... I only looked at Jupiter. There was a purple glow around the planet ... as large as the planet. The detail on the planet surface was excellent ...and on par with my skywatcher 120ED, but the aberration was just too annoying. This is a good looking scope and the quality is nice, except for the focuser which is terrible. Even the lock screws couldn't keep the fine focus from slipping.
