Hello Guys,

Anyone here who can tell me what is the thread in the Vixen FL55SS Astrograph in order that I can reduce it to an T2 Ring (M42), M48 works also for me. I think is M60 the thread, but I'm not sure and that information on the internet is clarely vague. Can anyone help me with that?

Cheers and clear skies
