Features of William Optics 2" VR Violet Reducing Filter WA-VR1-2:
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.
It's particularly suited for color and black & white photography. It works by absorbing light in the violet spectrum (around 400 nm) for more pinpoint, "APO" star views.
Quality Glass
• 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!
High Quality Finish
• Carefully machined aluminim body.
• Laser engraving.
APO Views
• Reduces false colour to a nearly APO level on bright objects like the Moon, Venus, and bright stars.
