      Hello,
      Here is a list of some useful accessories for the FeatherTouch 3545
      focuser that comes on several models of TMB refractors for anyone
      interested or thinking about purchasing. I use all the ones listed
      below and they are very high-quality and work great:

      1) Starlight Instruments "AP Endcap"--replaces standard clamp ring
      endcap and has the standard AP 2.7 inch female threads: $67

      2) Astro-Physics 2.5 inch threaded extension piece (PN A1008):
      http://www.astro-
      physics.com/products/accessories/focus_adap/focus_adap.htm#4 ($30 ea)

      You'll need two of them for certain camera configurations. They are
      stackable, very rigid, and precisely machined. They thread directly
      into the AP Endcap mentioned in #1 above.

      3) AP 2 inch male threaded adapter for SCT accessories (PN ADA204)
      $40:
      http://www.astro-
      physics.com/products/accessories/focus_adap/focus_adap.htm#7

      Threads into the Starlight Instruments "AP Endcap" (see #1 above),
      and may be stacked with the extender pieces mentioned above in #2.
      Use to attach 2 inch SCT accessories such as SBIG's AO-7 captains
      wheel.

      4) AP 2-inch 3-knob clamp-ring adapter for attaching eypieces, star
      diagonals, Barlows, and other accessories (PN ADA2003) $50:
      http://www.astro-
      physics.com/products/accessories/focus_adap/focus_adap.htm#ada2003

      With the above assortment of adapters, you can attach about any type
      of typical imaging CCD or webcam camera, Barlows, diagnonals and
      eyepieces very rigidly and safely.


      Hope this helps,
