Does anyone know the thread size off the Skywatcher standard R&P focus tubes, if one was to remove the standard 2" collar with the standard set screws on it?

 

I am wanting to replace this with a Baader click lock and want to make sure i order the right one. Scope is not in yet, so want to solve this before arrival! 

 

Thanks in advance if anyone knows! I know Baader has a M57 for Skywatcher/Synta, but not sure if that is the one I need. 

 

Cheers,

 

Darren

Contact Skywatcher or Skywatcher USA.  I'm sure they can answer your questions quickly.

Just heard back and also verified with my Buddies' Orion 80ED stock focuser. M56 male threads. 

 

So for those curious, the stock R&P drawtube has M56 threads when the 2"-T2 collar is threaded off. 

 

For those wanting one - the correct Baader click lock adapter is:

 

#2956256 - M56i x 1 threaded adapter
