Connector confusion

Hi All,

Is there a straightforward site somewhere that explains the different connectors used to couple equipment.

Particularly where two different names are used for the same connector.

M42, M48, 2 inch, 1.25 inch, C, CS  ........  bewildering.

Thanks,

My specific question would have been...
"Is M48 the connector to go on the internal thread of a 2 inch nosepiece."

 

But hoped to head off other queries by having a URL for somewhere that'd explain all the interconnects.

Although M42 and T threads have the same dimension the thread pitch is different https://en.wikipedia.org/wiki/T-mount in practice though some adapters that have only a few threads will screw together in fact to get my scope FF distance correct I used an M42 camera adapter together with a 10 mm long T spacer but I did use some loctite to ensure a good bond.
