Urth 72mm Stellar Filter Kit 4 6 8 Point Star Filters

SKU CH-NSRX-KP7T1

A 72mm kit with 4-point, 6-point and 8-point star filters that turn bright light sources into starbursts without affecting exposure

  • Transform light sources into 4, 6 or 8-point stars for creative effect
  • Japanese AGC optical glass with 8-layer nano-coating for sharp images and protection
  • Ultra-slim magnalium rim prevents vignetting on wide-angle lenses
  • Double-threaded design allows stacking with other 72mm filters
  • Works best with strong, nearby, partially obscured light sources

72mm Stellar Filter Kit

The Urth Stellar Filter Kit supplies three star-effect filters in 4-point, 6-point and 8-point patterns for 72mm lens threads. It is aimed at photographers who want to turn bright, nearby light sources into defined starbursts without changing exposure settings. The kit suits creative landscape, nightscape and portrait work where specular highlights can be emphasised for artistic impact.

Japanese AGC Glass with Nano-Coating

Each filter uses Japanese AGC optical glass coated with an 8-layer nano-coating that preserves sharpness and protects the front element. The ultra-slim magnalium rim is designed to avoid vignetting on wide-angle lenses while remaining lightweight. Double-threaded frames allow stacking or the attachment of a lens cap without removing the filter.

Starburst Behaviour Under Sustained Use

The star effect is produced by etched lines on the glass, so performance stays consistent during long sessions or time-lapse sequences. Aperture shape influences the result, with polygonal blades rendering more pronounced rays than circular ones. The filters do not reduce light transmission, so exposure remains stable even when shooting continuously in bright conditions.

Questions about this item

How do I install the 72mm star filters without causing vignetting?

Screw the ultra-slim magnalium rim directly onto the lens front thread; its low profile prevents vignetting on wide-angle lenses.

What maintenance will the Japanese AGC optical glass and nano-coating require over time?

The 8-layer nano-coating resists smudges and water; clean with a microfibre cloth and lens fluid — no re-coating needed.

Which light sources produce the strongest 4, 6 and 8-point starbursts with these filters?

Bright, nearby, partially obscured sources such as sunlight through tree canopy create the most pronounced star effects.
