Question Common Astro Equipment thread sizes

I have just purchased a small lathe and Milling machine to use to make some adapters for my gear and some modelling.
I have spent some time trying to find thread sizes and pitch for some common astro equipment to almost no avail.

It might be good to put together a table with some of the common thread sizes for items like, filter threads, SC rear cell threads, Standard Tak threads, Focuser threads and the list could go on and on.

If you know any thread sizes commonly used, please post them here and I will put them all together in a document and ask Mike to post it in the projects and articles section for everyones use.

Thanks in anticipation.
