Product Description
This adapter is made to work with our standard 3.5" focuser, the Feather Touch 3" focuser and other focusers with an M75X1 threaded drawtube or adapter. It will not fit onto other thread sizes.
This 2" adapter does many things.
- It serves as a rotating 2" visual back for focusers that have an M75 female thread.
- It is a 360 degree rotator with nylon bearing surfaces.
- Unthread the 2" back and it will accept the newer versions of the two inch, .8X reducer/flattener or any accessory with the M54 X .75 thread.
- Unthread the first knurled ring and you have an M68 X 1 thread which accepts many flatteners including our SFF3 and SFF4 series.
Cnc machined and black anodized finish.
This rotator has three configurations. It is 20.75 mm in length when using the 68 mm female connection, 25.15 mm long connecting to the 54 mm female thread, and 37.25 mm long when using the 2" compression clamp. It has six nylon bearing screws, a Teflon thrust bearing and a thumb screw to lock rotation.
