Takahashi 4" Field Flattener for Takahashi TOA-130NFB & TOA-150

Takahashi The 67-FL Flattener



The Takahashi 67-FL flattener is designed to be used with either the Takahashi TOA-130NFB and/or the Takahashi TOA-150 refractor. Both telescope have unique connections, so a #83 coupling ring is also included in the package which will allow it to adapt to both telescopes or the extension tube.

Get a great flat field with whatever type of system you use!

Completely agree with Greg

This flattener made a WORLD of difference from the stock telescope. The images I'm getting with an STL-11000M are astounding with this!

Do Not Leave the Store Without It

This is an amazing piece of glass, which transforms both the visual and imaging experience when using the TOA-130 NFB. The field curvature of the TOA *must* be corrected for a satisfying imaging or viewing experience, and other flatteners just do not work nearly as well -- believe me, I have tried. The 67-FL is very forgiving of backfocus distances when used with smaller imaging sensors (up to about 24 millimeters diagonal, and with larger sensors is absolutely required. It is a must-have for imaging of any sort at the native focal length, and is really a should-have for visual use as well, flattening the visual field in a way that thoroughly delights the eye. Even though it adds nearly $1000 to the cost of an already-expensive refractor, your TOA-130 just will *not* live up to its potential without a matched flattening element in the optical train. Takahashi should not allow the TOAs to be sold without this device. Do NOT purchase a TOA refractor without one of these!
