Explore Scientific 3” Flattener & 0.7X Reducer
for 127 mm & 152 mm Triplet Refractors



When you attach the Explore FFFR507X-00 to your Explore 127 or 152 refractor telescope, it will improve the flatness of the field & reduce the telescope's effective focal ratio by .7X. A flat field translates to sharper, more pinpoint stars out to the furthest reaches of the field of view, and reducing the focal length creates a wider field of view and, when imaging, allows for shorter exposure times. The back focus is 55 mm as measured from the rear flange.



The Explore Scientific 3” Field Flattener & .7X Focal Reducer is fully multi-coated for a high level of clarity and brightness, and comes with a M42x0.75 adapter to help you attach your DSLR or CCD camera. If attaching a DSLR, please note that you will still need a T-ring for your camera brand. The extra photo at left shows all of the components…the focal reducer/field flattener body, a 3” nosepiece, and the M42 adapter.

  • Weight: 1.4 lb.

  • Height: 90.1 mm

  • Back Focus: 55 mm from rear flange

Please Note: Explore designed this focal reducer and flattener for their f/8 refractors but testing has proven that it performs nicely with their f/7.5 refractors as well.
