<strong>Astromart</strong> <strong>Reviews</strong> - <strong>William</strong> <strong>Optics</strong> <strong>FLT110mm</strong> <strong>f7</strong> <strong>TMB</strong> <strong>designed</strong> triplet and matching field flattener<br />
The same test on the <strong>TMB</strong> 105mm refractor with <strong>TMB</strong> field flattener gave a value of around 16% curvature, but<br />
the curvature cone was not centred on the optical axis, giving a slight asymmetric result over the 35mm format.<br />
As mentioned, with an adapter ring made by a friend of mine, I could also test the Takahashi TOA/TSA 2.7?<br />
reducer-corrector to work at approximately f 5.3. On the image below you can see how the TOA reducer is<br />
adapted to the <strong>William</strong> <strong>Optics</strong> focuser:<br />
