We no longer offer this unit. This is the former, imported, generic Flattener/Reducer which we sold for use with the SVX102T and SVX102T-R. When used with the older model SVX102T's and the former SVX102T or SVX102T-R, this unit will not come to focus. We had to shorten the main tube to accomodate this reducer/flattener when it appeared on the market.
The reducer flattener comes with an extension tube and camera thread adapter. Without these two parts, the back focus with the SVX102T is 68 mm. It comes with a 10 mm extension tube and adapter that takes up 3mm. So with these in place the back focus is the standard 55 mm from the base of the camera thread to the sensor. This reducer/flattener converts the 102 mm f-7 714 mm focal length objective into a 102 mm 530 mm focal length f-5.2 wide field imaging scope. Merely un-thread the adapters from the focuser draw tube and thread this unit onto the focuser's draw tube.
With this model, on the camera side there is a 10 mm extension tube and an adapter. With these left in place this system has a standard 55 mm back focus as measured from the base of the camera thread on the supplied adapter. If the extension tube and adapter is removed, the total back focus of the reducer/flattener is 68 mm.
