Have a 2" GSO refractor diagonal (standard or dielectric) that you want to use with your SCT or Mak telescope but cannot? Here is the solution you need! In response to requests from several customers, we now offer just the SCT barrel from 2" GSO SCT diagonals.
You can simply unscrew the chrome barrel on the telescope end of your GSO refractor diagonal. Then insert this barrel in its place and you can now use your refractor diagonal with all telescopes having a standard SCT thread.
