Hi RodStar,
This topic may explain the odd shape of your focus knob that i experienced on Saturday Night.
I have severe mirror shift in my scope, and focusing is becoming more of a problem of late.
How much was your Peterson kit? I have been talking to Mick Pinner and swapping Meade sob stories and Mick is putting me onto a focus fix for my scope. I can only try it and see. He is mailing me some information on this.
