Thank you all for the responses, it's greatly appreciated!

Hello, I have a question about thread sizes. I've looked around the internet the best I can but cannot find any information on what size of threads are inside the skywatcher 350p collapsable goto dobsonian, 14". I am looking for an adapter to screw into the focuser itself as opposed to relying on the set screws for more delicate equipment (almost had an oppsie, so now I want to be prepared for next night it's clear!) but cannot do that until I know what thread size the focuser tube will accept. Thanks!
