This is the Flattener/Reducer designed for the SVX102T and SVX102T-R using the 3" Stellarvue focuser. This reducer/flattener converts the 102 mm f-7 714 mm focal length objective into a 102 mm 535 mm focal length f-5.25 wide field imaging scope. Merely un-thread the 2" adapter from the draw tube on the focuser and thread this unit into the focuser draw tube.
With this model, on the camera side there is a 48 mm male thread and 55 mm of backfocus. So this reducer/flattener as it comes will work with a DSLR with a 48 mm t-ring. It will also work with a ccd camera that uses the M48 thread and has a 55 mm back focus. If your ccd camera uses another thread and/or if the back focus is not exactly 55 mm, please call us and we can provide you with a modified version of this reducer/flattener with the proper adapter to meet your requirements.
Please note: This reducer/flattener is larger in diameter than the inside of other brand 2.5" - 3" focusers. This includes the Feather Touch 3" focuser. Since it must thread into the focuser to reach focus, it cannot be used with any Stellarvue unless it came with a Stellarvue FSV-3 three inch focuser!
