Sparsile

I know this is old, but wanted to add an observation in case someone else comes across this. I just purchased an AT60ED and was wondering about the focus lock as well. The instruction sheet indicates that there is a "chrome lock knob under the focuser [that] lets you lock in that sharp focus." However, there is no chrome knob. The brass-colored screw in Space Oddities picture is the focus lock. It's not a chrome knob, but tightening it with a screwdriver prevents the focus from moving at all. The "big red knob" at the top is a "drag adjuster". However, I don't really feel much difference when I try to tighten it. If anyone has successfully replaced the brass screw with a chrome knob, please let me know!
