G'day Inkswitch, welcome to the site. Can't help you much with eyepieces but you need to remove the whole plastic cap from the end.
Incase you aren't aware on how to set up your scope, raise the axis closest to the tripod top to the latitude of Cairns (15 deg?
) and then point that axis towards the south pole. 'scuse me if you are already aware of this.
