10" - 16" GSO RC and CC truss telescopes (made after 2016) come with a tilt-adjusting assembly that has a built-in 25.6mm extension plate # FF390 that consumes additional back focus. This extension cannot be separated from the tilt adapter, so if you wish to gain additional back focus, you can replace the 25mm plate with this adapter FF354. This adapter is a shorter version of the FF390 and reduces the back focus consumed from 25.6mm to essentially 0mm.
Not for use with GSO's 10" and 12" closed tube scopes. Please also note that this ring is not compatible with the GSO FF672 tilt adjuster.
The FF354 plate is 14mm thick and the M117 male thread length is 9mm. The plate weighs 0.88 oz. Its maximum outside diameter is 154mm.
