Descriere produs

Din pacate, descrierea acestui produs nu a fost inca tradusa in limba romana, din acest motiv veti gasi in loc o descriere in limba engleza.

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. It 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 tripllet APO design.
Produced entirely with the best Ohara optical glasses.

Amazing

Reducing factor 0.8X

48mm filter ready

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.

Suitable for: GT71, GT81, Z81, Z103, Z126 (GT = Gran Turismo, Z = ZenithStar)

You have to adjust the flattener to your telescope:

GT71: 9.1mm
GT81: 7.1mm
Z81: 5.2mm
Z103: 2.5mm

The pictures on the right shows how this is done: Just turn the flattener until the scale shows the correct distance, than lock it with the locking ring.

How to install the flattener? The flattener comes with an M63 thread. You just have to unscrew the 2"-Adapter out of the tube and screw the flattener inside.
