This new 0.8x reducer/flattener works well with both the SVX070T and the SVX080T. It will correct past APS-C, and has a variable back focus adjustment. At long last we have a reducer flattener that works with fast refractors and it can be dialed in to work.
With the variable adjustment you can dial in back focus to match your camera and telescope. Lets assume you have our 80 mm f-6 apo triplet (any version that uses a 2.5" or larger focusers). Lets also assume you are using a DSLR with a 55 mm back focus. Merely dial the adjustment to around 6.5 and your back focus will be close to optimized. Experiment from there and dial in the flattest field!
Now lets assume you have the Stellarvue SVX070T. Dial it to 9 mm and start from there.
The focusing mechanism is tight and smooth but once you have it dialed in, use the thumb screw to lightly lock it in place.
Camera-side threads = M48
Focuser-side threads = M63
*If you have a scope with our 3" Stellarvue Focuser then you will need the following adapter in order to connect to this reducer:
SFA-M68F63-005 Adapter - Male 68mm to Female 63mm
This reducer/flattener is also capable of housing 2" mounted filters. As seen below you simply unthread the adapter on the camera-side of the unit, attach the filter, and reassemble everything!
*Please note that we do not recommend stacking filters as there will not be enough space to accommodate more than one.

After a short session followed by the instructions from Stellarvue. This Reducer/Flattener got right to the optimum spot where they said it would be. This is a clear testament that they indeed tested every single scope during and prior to being shipped to customers to be absolute of their best designed performance.
