  1. Wayne W. Verified Buyer –

    I bought a new sky-watcher 8″ f/4 newtonian and immediately tore it down to do all the mods. One was replacing the secondary spider and adding bobs knobs. They work great and a complete collimation is about 60 seconds now with the laser Collimator. I highly recommend replacing the original screws with Bob’s Knobs.
