      I ordered two different M48X0.75 and M42X0.75 male to female adapters. They were exactly as advertised, threaded to other devices with no problem and exhibited excellent fit and finish.

      5.0 2" filter adapter to T2

      Pros:

      Cons:

      Comments:

      A pair of adapter rings to adapt 2" filter to T2 mount cameras. Well finished, threads with proper size and pitch. Woks perfectly to use my 2" mounted filter with QHY10 camera T2 mounted.

      5.0 Adapter

      Pros:

      Lightweight,Strong Construction,Easy to Use,Accurate

      Cons:

      Comments:

      This was one component in a custom setup of 4 parts I built to use with a Canon lens for afocal astrophotography.
      This adapter allowed me to connect the front part that attached to the eyepiece to the back sections that screwed into the camera lens.
      It all worked out very well.
