Hi Steve,
Vega is a pretty tough test subject. It can be pretty difficult to accurately asses the rings with an achro due to the out of focus secondary colour. If you have a dark green or dark yellow filter you may want to try it again with a not so bright star. Pick something well above the horizon, mag 2-3 and make sure seeing is steady.
