Milky Way vs Star Cluster: Night Sky Filter Showdown

Compare the Milky Way anamorphic flare filter and Star Cluster kaleidoscope prism filter for night sky photography. Find out which effect filter suits your creative vision.
Quick answer
Choose the Milky Way filter if you want dramatic horizontal blue flares that mimic anamorphic cinema in night scenes. Pick the Star Cluster prism filter if you prefer kaleidoscopic reflections that multiply your subject into symmetrical patterns. Both add cinematic flair, but their visual effects are fundamentally different.
How each filter transforms your night sky shot
The Milky Way effect filter uses parallel blue stripes across the glass surface. When a strong point light source hits these lines, they produce dramatic horizontal flares — exactly like classic anamorphic cinema lenses. This works beautifully with streetlights, stars, or any bright point in a dark sky, turning simple frames into wide, atmospheric visuals.
The Star Cluster prism filter takes a completely different approach. It refracts and multiplies your subject into a mesmerizing pattern of symmetry and motion, inspired by astronomical geometry. Instead of adding streaks, it creates kaleidoscopic reflections that make a single subject appear as a cluster of repeating shapes — rich in rhythm and energy.
Both filters feature the RFL Infinity Ring™, which spins endlessly after mounting, so you can rotate the effect without removing the filter. This is especially useful for aligning horizontal flares or adjusting the kaleidoscope pattern in-camera.
Key differences at a glance
The Milky Way filter adds blue-colored streaks to highlights, which can shift the color tone of your scene slightly. It's designed for creators who want a bold, immersive cinematic look without post-processing. The Star Cluster filter keeps the original colors of your subject but fragments the composition into repeating reflections, making it ideal for abstract or surreal night sky imagery.
Trade-offs to consider
- Flare direction vs. pattern symmetry: The Milky Way filter forces all flares into a horizontal line, which can be limiting if you want vertical or diagonal streaks. The Star Cluster filter gives you symmetrical repeating patterns that you can rotate freely with the Infinity Ring. Choose Milky Way for cinematic horizontals; choose Star Cluster for geometric symmetry.
- Color shift vs. color preservation: Milky Way adds blue tones to your highlights, which may clash with warm scenes or require color correction in post. Star Cluster keeps your original colors intact, only multiplying the subject. If you need neutral color reproduction, Star Cluster is safer.
- Point light dependency: Milky Way needs strong point-light sources to produce visible flares — dim ambient light won't trigger the effect. Star Cluster works with any well-lit subject, even in lower light, as long as the subject is distinct. For dark night skies with few bright stars, Star Cluster is more reliable.
Product facts
- Milky Way: Blue streaks. Anamorphic glow. MILKY WAY is an anamorphic-style flare filter featuring parallel blue stripes across the glass surface. When hit by strong point-light sources, these lines create dramatic, horizontal flares — just like in classic cinematic scenes. If you want that signature anamorphic lens look without renting expensive cinema glass, this filter delivers blue horizontal flares directly in-camera.
- Star Cluster: One subject. Infinite reflections. STAR CLUSTER is a classic kaleidoscope filter that refracts and multiplies your subject into a mesmerizing pattern of symmetry and motion. Inspired by the geometry of astronomy, it transforms ordinary scenes into bold, fragmented compositions. When you want to turn a single star or moon into a repeating visual pattern, this prism filter creates instant abstract art without any editing software.
Which one fits your style?
Best for
- Filmmakers and photographers who want an anamorphic cinematic look with blue horizontal flares
- Creators shooting cityscapes at night with plenty of streetlights or bright stars
Not for
- Those who need neutral color reproduction without blue tint in highlights
- Shooters who prefer abstract kaleidoscopic patterns over linear flares (choose Star Cluster instead)
