Looking for Celestron Edge HD 8" Bob's Knobs collimation thumb skews.
Does anyone know who sells them in Australia ?

I wound up buying mine from the states, took 5 weeks or so to get here.

I bought some from Sirius Optics. They certainly advertise other Bobs Knobs so maybe give them a call.

Also, just upgraded mine to the stainless steel version. The regular onesdo corrode a little over time making themhard to turn, the SS ones are really smooth!
