William Optics FLT91 Flat6A III Special Edition

The William Optics FLT91 Flat6A III flattener takes your astrophotography to the next level. This lens corrects the curvature in the field of view of your FLT91 telescope. Without a flattener, stars are stretched and out of focus toward the edge. With this flattener, stars remain sharp and round all the way to the edge.

This specially calculated flattener is matched to the FluoroStar FLT 91. You easily mount it between your telescope and camera. The included adapter ensures that everything fits perfectly. The optimal distance from camera to flattener is 5.4 mm, so your sensor is exactly in focus.

Use the flattener especially with large cameras and small focal ratios (f/5-f/7). This way you get maximum sharpness out of your images. The result: star-sharp photos of deep sky objects, without distortion or stretched edges.

In short, the Flat6A III makes your FLT91 ideal for serious astrophotography with DSLR or CCD.
