Undo the ring anticlockwise (it has notches all around it) behind the front lens assembly and wind out the whole front lens assembly until you get sharp stars. Lock the front lens assembly by tightening the ring behind it.

I usually remove the whole finderscope and look at a bright star through it while holding it with one hand and winding out the front lens assembly with the other hand. If you look at Acrux, keep winding it out until you can clearly see two stars - a bright one and a dimmer companion.

Regards, Rob
