Astrophotography Fit

Best as a specialty planetary or lunar contrast filter, not a general deep-sky filter.

ZWO UV/IR Cut 2-inch Filter is a budget-friendly UV/IR cut filter (2"). Passbands: Visible 400-700 nm.

Best as a specialty planetary or lunar contrast filter, not a general deep-sky filter.

Choose filter size around the sensor diagonal, telescope speed, and filter-wheel or drawer geometry. Flats are still required; a filter can improve contrast, but it will not rescue tilt, bad focus, or poor calibration.

Best paired with

  • Monochrome planetary cameras and long focal length scopes
  • Good seeing, high-frame-rate capture, and derotation/stacking software
  • Lunar or planetary sessions where IR contrast is useful

Not recommended for

  • General color deep-sky imaging
  • Visual observing without a clear contrast purpose
  • Beginners looking for their first all-purpose filter
