About this product
Part Number: A-F156GTGD-RP37
Optical Bench Test
FLO tests all William Optics triplet refractor telescopes before dispatch.
You can be confident your telescope will, from the outset, have well figured optics, negligible false colour and spherical aberration, and no astigmatism (the bane of any optical system!).
Star shapes will be round, not triangular, oval or egg-shaped!
The William Optics Fluorostar 156 is a 3 element designed APO Refractor using an FPL53 extra low dispersion glass element with matching Lanthanum element.
This combination provides 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 and Pinnion 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 is a trio of beautifully anodised CNC made tube rings and 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.
We recommend storing the telescope in a dry place with consistent room temperature when not in use.
