This very elegant 2" reducer/field flattener has been designed to optimize the flat-field imaging performance of William Optics F/6 to F7.5 ratio refactors. WO Flat 6All will provide good illumination and flat field across 97% of full frame sized sensors.
Full frame size
- Designed with nearly full frame chip-size DSLR cameras in mind.
- FMC triplet APO design.
- Produced entirely with the best Ohara optical glasses.
Amazing
- Reducing factor 0.8X.
- Adjustable design, for perfect back focus it can be used with other models of refractors
Superb Finish
- William Optics polished anodized finish.
- All internal surfaces threaded and blackened to prevent reflections.
Easy to Use
- Will accept any standard 48mm T-ring for your camera (not for use with 42mm T rings)
- Weighs 15.3oz
Suitable For
- Z71, GT71, GT81, Z103, Z126
Adjustment Distance
- Z71: 11.8mm
- GT71: 9.3mm
- GT81: 7.9mm
- Z103: 4.6mm
- Z126: 1.4mm
- Graduated millimeter scale on the flattener allows you to set the correct spacing distance for your telescope. A lock ring securely holds the spacing distance in place.
How to Attach Flat6AII to Telescopes
- This flattener/reducer does NOT come with a standard 2" nospiece (sold separately if required)
- On the telescope side, this flattener features an M63 male thread as well as an M48x0.75 female thread.
- Some William Optics telescopes have an M63 female thread on the eyepiece side. This flattener/reducer can be screwed directly into those telescopes without any modification or additional parts. In this configuration, the M48 female thread on the flattener/reducer can also accept a 2" astronomical filter.
- However, for use with 2" focuser drawtubes, you need to purchase and attach the William Optics DIG2A 2" nosepiece (or equivalent) to the M48 female thread of the flattener/reducer. In this configuration, you cannot attach 2" filters to the flattener, although you can attach one to the 2" nosepiece.
