T-Thread Adjustable Metal Spacer Locking Rings

T-Thread Adjustable Metal Spacer Locking Rings


Customer Reviews

  First class addition to my accessories collection  This is a really useful spacer to have when setting the back-space between focal reducer and ccd focal plane. This being due to the fine adjustments that you can then lock into place.  (22/09/2017) Dave - Hampshire, England


  Well made variable spacer  I'm converting my Celestron RACI finderscope into a guidescope, but with the adapter I needed extra 22mm. With a couple of other spacers, this variable spacer allowed me to orient the guide camera with the main scope and lock it within the adjustment range of the focuser. Perfect.   (17/06/2017) Mike Curran - Devon
