If your FLT refractor from William Optics comes with a heavy camera with a filter wheel, you quickly notice whether the focuser can handle it. If you want to replace the original focus ring with a 3.5-inch focus ring from Starlight Instruments, such as a Feather Touch, this focus adapter will connect the William Optics FLT.<\/p>\n\n\n\n

The adapter comes between the tube and the new focus lens. The FLT series is widely used for photography. You can find more of this type at our store. Refracting telescopes<\/a>.<\/p>\n\n\n\n

Check beforehand that the connection on the back of your FLT matches this adapter. If in doubt, measure the wire or flange. If you are using a flattener like the William Optics's adjustable Flat6A III<\/a>, Then set the distance to the camera again after the conversion.<\/p>\n\n\n\n
