ZWO Blocking Filters UV/IR 1.25"

ZWO UV/IR Blocking Filter 1.25 inch: Sharper Stars and Pure Colors

Many CMOS color cameras are sensitive to ultraviolet and infrared light. This sounds like an advantage, but UV and IR fall outside the focus range of most lenses and cause color fringing and halos around stars. This UV/IR-cut filter allows only the visible spectrum to pass through, solving these issues in one go: sharper star edges and natural color balance.

When do you use this filter

• For color cameras without a built-in IR-cut filter, such as the ASI294MC, ASI533MC, and ASI585MC
• With refractors and lenses that are not fully apochromatically corrected
• As an additional safety filter for solar photography with solar film or a Herschel prism

Compatibility

Fits all 1.25-inch focusers, filter holders, and filter wheels. Suitable for photography and visual use.

Specifications

A small filter with a big effect from the filter series of ZWO. With almost any color camera on a refractor, this is the first purchase.
