Description

M42 Adapter

The Stellarvue SFFR.72-130-25-42 Reducer/Flattener threads into the 2.5" focuser version 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 M42 male thread for the camera.

This giant reducer/flattener will convert the 130 mm f/7 visual optical system in the SVA130T to a 130 mm f/5, 650 mm focal length imaging system. The basis of this dedicated system is the SFFR.72-130 reducer flattener. While it has 55 mm of back focus with the included adapters, should you choose to use this unit without the adapter you will have approximately 70 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. 

M48 Adapter

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.
