The new William Optics Fluorostar FLT 156 is a three element air-spaced apochromatic refractor with a focal ratio of f/7.8 and a focal length of 1217mm. Utilizing FPL-53 synthetic fluorite and Lanthanum glass with STM coatings, this telescope provides excellent aberration correction and amazing optical performance.

The 3.7" dual speed rack & pinion focuser is smooth, stable and reliable, providing no slippage over long imaging sessions. The super smooth field rotator includes markings for every degree, and a solid thumbscrew position lock.

The CNC-machined and anodized handle bar with Vixen-style saddle is perfect for attaching a guide scope or other accessories. The FLT 156 also includes William Optics' innovative clear Bahtinov mask integrated into the lens cap. The Rotolock 2 inch adapter provides for a solid and efficient connection for a William Optics 2 inch diagonal, and other accessories.

William Optics uses high quality steel lens cells for their Gran Turismo and FLT triplet refractors. This is perfect for temperature compensation and will prevent pinched optics in cold weather conditions.

For best imaging results, it is recommended to pair the FLT 156 with its matching Flat68III 1.0x field flattener, Flat7A 0.8x reducer or Flat8 0.72x reducer.
