![Photographic Field Flattener for SVX152T-35SV (SFF4-152T-35SV)](http://cloudbreakoptics.com/cdn/shop/products/SFF4-152-35SV__93713.1542404880.1200.1200_{width}x.jpg?v=1543971129)
This full frame field flattener is made specifically for the SVX152 with the Stellarvue FSV35 3" focuser.
On the camera side of this flattener is a standard M48X.75 thread. The backfocus from the base of this thread is 55 mm. So this 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 flattener with the proper adapter to meet your requirements.
This flattener can work with former Stellarvue 152 refractors that use a 3.5" Feather Touch focuser with this adapter.
