Why W.O. diagonals do not feature an Adjustable alignment system?

2" VR-1 Violet Reducer Filter
The WO VR-1 is a 2 " Minus Violet filter that tremendously reduces the effects of chromatic aberration (purple halo and blue glow) that achromatic refractors return on bright objects.

• Decrease violet fringing to a nearly APO level while still providing good transparency in the rest of the spectrum.
2 Inch
• Threaded to fit all threaded 2 " eyepieces and diagonals. Very convenient when used together with WO 2" Diagonals!
