Model: WO-flt-151-FTBrand: William Optics
The William Optics FLT 151 features a fast F6.7 APO Triplet objective lens with Japanese Ohara FPL-53 glass.
Superb colour correction, resolution and contrast make the FLT 151 an excellent choice for astro imaging and critical visual observing.
When used with the WO Flattener IV at F5.36 the FLT-151 delivers a flat field suitable for C-size sensors.
The Starlight Instrument 3.5" Dual Speed Feathertouch Rack and Pinion Focuser is generally considered the 'best' refractor focuser available with excellent load bearing capacity.
Complete with CNC tubes rings and both 2" and 1.25" adaptors.
