About this product

The William Optics Fluorostar 156 is an apochromatic refractor telescope with a triplet optical design that includes an FPL53 extra-low dispersion glass lens with a matching Lanthanum element for outstanding colour and aberration correction. 

Details and Features

Includes a WO-designed anodised CNC-made Handle Bar. This is compatible with the William Optics Uniguide Guide scope.

The FLT156 features a 3.7″ Rack & Pinion Focuser, providing smooth, stable and precise focussing with no image shift. It is compatible with the WO 3″ Field Flattener.

Also included is a patented Bhatinov mask that is three times lighter than Bhatinov masks made with conventional materials.

Also included are a trio of beautifully anodised CNC-made tube rings and a Losmandy-compatible mounting plate.

The FLT156 is compatible with the William Optics Flat 6AIII – which provides the best image quality – the Flat 7A 0.8x Reducer/Flattener and the Flat-8 0.72x Reducer/Flattener.

The FLT156, in common with William Optics FLT132 and GT Triplets, uses a high-quality steel lens cell that is less prone to thermal movement and lens pinching in low temperatures. Nevertheless, we recommend storing the telescope in a dry place with consistent room temperature when not in use.
