This 2.5” Dual Speed, Fully Rotating, Rack and Pinion Focuser with adapter that connects to Orion, Synta, Skywatcher ED80 and others. Not sure if it fits? Check the drawing below showing the adapter then remove your focuser and measure the part that goes ionto the tube. Dimensions should match. Some import parts vary so it may be possible that a small round file is needed to better line up the holes.
Simply remove the stock Synta forcuser by removing the three screws that pass through the main tube. Insert this adapter in its place and the focuser above will thread directly into it. This adapter will work with the Synta or Orion 80ED or 120ED telescopes that use the standard Synta Crayford focuser.
If you are not sure if this focuser will work with your telescope, remove the focuser and measure the part that slides into the telescope. Above is a drawing of our adapter. The left side of the adapter slides into your tube or adapter and the focuser threads on the right side. All measurements are in millimeters.
