Collimation knobs
Apologies for what I'm sure is another version of many already-existing threads.
Looking for new collimation knobs for a Skywatcher 8" f/5, an old one that has the rotten old allan key screws for both primary & secondary. Bob's Knobs' website lists Bintel as the local supplier, but Bintel tells me they don't have them now that all new reflectors have the proper knobs included as stock.
Any idea where I might track some down?
