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.
Bintel don't do Bob's Knobs anymore, but I found another place in SA that does them for a reasonable price. Being posted out today. Hooray, no more fiddly Allen keys.
