Product Description
The Stellarvue SFFR.72-130-25-48 Reducer/Flattener threads into the 2.5" focuser of the SVA130T and provides .72X reduction, converting the 130 mm f/7 system into f/5 for wide field imaging. This version of the reducer/flattener comes with adapters that provide 55 mm of backfocus with an M48 male thread for the camera. Should you choose to use this unit without the adapters you will get approximately 69 mm of back focus using the M69X1 rear thread.
This full frame reducer/flattener has been responsible for many of the amazing images taken recently with the SVA130T.
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.

Expensive, but works really well
I bought this for my Stellarvue SVA130T with 2.5" SV focuser. It's not cheap but it works very well. Stars are great to corners in my APS-C DSLR sensor (a first for me as I usually see some elongation with other reducer flatteners over the years). It's larger and heavier than I expected, probably weighs about 3.5lbs. My SV focuser seems to handle it with no issue though.
