Fantastic quality as usual from William Optics a brand to trust. I needed this to reduce my focal length down for astrophotography. It Works very well it must be said. As usual, the delivery was quick, it was well packaged and safe on arrival. Thanks to all at FLO.

As a relative newbee to astronomical hardware, the simple act of interfacing a camera or your eye to a telescope can be a minefield of different thread sizes, adaptors, and extension tubes, to make everything work. A field flattener ensures the outer regions of your field of view is as crisp as the centre, and this adaptor is necessary to connect correctly the William Optics field flattened to their WO71GT telescope. Other WO telescopes fit differently and do not require this adaptor So, DO as the experts (like FLO) if this is the correct adaptor for your own set up.
That said, the product arrived safely, quickly, is well made and works perfectly, as I expect of WO. FLO were responsive in reassuring me that this was the right solution for me.
