loose power cable connection on NexStar 8i

I just got a new NexStar 8i. It's my first scope. I also have a celestron power tank with the supplied cable. The connection on the scope is not very tight. When the cable moves, such as when the scope is slewing, the connection gets jiggled, which causes the power to be interrupted. This causes me to lose my alignment and I have to start over. This is extremely frustrating.

I just put a piece of duct tape below the cradle for the hand control, and attached a velcro strip to that. I can make a loop of cable between the connection and the velcro so that when the scope moves, the cable does not tug at the the connection. There has to be a better way.

Any suggestions?

Amy: I have a NexStar 8i and, although I've never had the problem you describe, I will pass along the following advice from "The NexStar User's Guide" by Michael W. Swanson:
"If you have problems with the power cord pulling loose when the scope slews, attach it to the fork arm with a large rubber band or a self-adhesive hook. Sometimes even this may not be enough. . . Many power cords seem to provide a good fit, but the inside hole of the connector is too large for the center post of the scope's power connector. One possible solution is to use a jeweler's screwdriver or a razor knife to GENTLY spread the center post of the power socket on the base of the telescope. Be careful not to twist the post as you perform this delicate operation -- you could break the connector inside the scope, necessitating replacement of the entire power socket. A better solution is to replace the connector on the power cord. The correct connector for NexStar scopes has an outside diameter for 5.5 mm and an inside diameter of 2.1 mm. While a loose-fitting connector might seem to work, hard-to-diagnose problems often occur."
