Sony/Minolta A-Mount to focuser

[FrenchyArnaud]

Hi everyone, 

I have a Sony Alpha300 (A mount = Minolta AF, NOT MD) and I want to use it for astropics. 

I have telescopes with1"25 eyepieces. None seem to have threaded focusers.

Now, I am a bit confused between Trings, T2rings, M42... I gather I need an adaptor to put instead of the eyepiece, then a ring that will fit on it and on the A-mount.

Is someone able to direct me to some ebay stuff (or other!) to the correct bits I need ? 

Thank you very much !

The t ring you need is the Sony Alpha t ring . Also a  1.25" t mount camera adapter.
