Hi Petra, I've been in contact with Bob from Bob's Knobs in the U.S. He's just about to release a set of Primary and Secondary collimation knobs for the LB scopes.
Once you have your secondary properly lined up it's unlikely to need recollimation unless you pull it apart or it receives a severe hit, so you shouldn't need these.
You should only need the primary knobs.
Bobs done all the hard work for us and it will mean less running around for you. With the price of petrol now it's a good idea.
Bintel are the Australian distributors.
