This giant reducer/flattener will convert the SVA130's f-7 visual optical system to a 130 mm f-5 (650 mm focal length), full frame imaging system. The basis of this dedicated system is the SFFR.72-130 reducer flattener. This unit has a 69 mm back focus using an M82X1 rear thread. This full frame reducer flattener has been responsible for many of the amazing images taken recently with the SVA130T.
This version of the SFFR.72-130 is designed for use with the 3" Feather Touch focuser. Adapters will be needed to obtain proper spacing from your particular camera.
The SFFR.72-130 threads into the 3" Feather Touch focuser once you remove the 2" adapter. The rear thread is M82X1 and the backfocus of the system is 70.5 mm.
Questions? Call us at (530) 823-7796. We have hundreds of machined threaded adapters now in stock and we can outfit this reducer flattener for practically any camera on the market.
PLEASE NOTE: This unit is designed specifically for the SVA130T. It is not designed to work with other 130 mm refractors unless they have a removable 55 - 60 mm extension in front of the focuser as shown in pictures to the right.
Please note: While the pictures to the right show a 2.5" focuser
the procedure remains the same if using the 3" focuser.
