Description

The new FC/FS Multi-Flattener 1.04X is designed as a universal replacement to previous flatteners in the FS and FC series of fluorite doublet telescopes.  The flattener is a two element design that greatly improves the field curvature present in doublet telescopes.  This flattener works now only with all FS and FC telescopes currently in production, but also works with many older models.  Each telescope model requires a specific CA ring, as specified in the appropriate system chart.

The flattener is compatible with the following telescopes, and results in the indicated image circle.

Customer Reviews (4.6 / 5 · 5 reviews)

George ★★★★★

Finally got sharp stars across the full frame with my FS fluorite scope, and the 1.04X magnification is perfect for my imaging setup. The two-element design really cleaned up the coma in the corners.

Edward L. ★★★★★

Had a tough time dialing in star shapes with my previous flattener, but this one gave me crisp stars across the whole frame on the first try. The two-element design really makes a difference, and it feels solidly built.

Richard ★★★★★

Swapped out the old flattener for this two-element design and the star shapes are perfectly round across the whole frame. My FS-60C shots look noticeably sharper now, especially at the edges.
