This is the flattener/reducer designed for the photo-visual SVX80T-3SV using the 3" Stellarvue focuser. This flattener/reducer converts the 80 mm f-6 480 mm focal length objective into a 80 mm 360 mm focal length f-4.5 wide field imaging telescope. 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 back focus. So this flattener/Reducer 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 flattener/reducer with the proper adapter to meet your requirements.
Please note: This reducer/flattener is larger in diameter than the inside of former Stellarvue 80 Apos that used 2' - 2.5" focusers and 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!

Sweet! This device produces pinpoint star images out to the edge of my APS-C sensor (28 mm diagonal), though I think the actual image cicle is much larger, approximately 44 mm. This device operates as advertised. Highly recommended!
