Product Overview
The SVBONY SV155 is a set of seven 1.25″ filters for lunar and planetary observing: five Wratten-numbered colour filters (#12 deep yellow, #21 orange, #23A bright red, #56 bright green and #82A light blue), a moon filter and a CPL (circular polarising) filter. Each sits in a 2 mm aluminium cell with standard M28.5 x 0.6 threads top and bottom, so they thread into a 1.25″ eyepiece and can be stacked.

Who It's For
This is a good match if you observe the Moon and planets visually and want to bring out surface and atmospheric features that colour filters isolate, or to tame the brightness of the Moon.
Key Features & Design
- Seven filters: five planetary colour filters, a moon filter and a CPL filter.
- Standard 1.25″ threads: M28.5 x 0.6, fitting 1.25″ eyepieces and accessories.
- Stackable cells: threaded on both sides.
- Aluminium frames, optical glass.

Recommended Uses
SVBONY's guide to each filter:
- #21 orange: raises contrast between light and dark areas and helps show Jupiter's Great Red Spot.
- #23A red: sharpens boundaries on Mars, belt contrast on Jupiter, and surface detail.
- #56 green: enhances frost patches, surface fog and polar features on Mars, Saturn's rings, Jupiter's belts and the Moon.
- #12 yellow: helps show Mars's polar caps and clouds, and red and orange features on Jupiter and Saturn.
- #82A blue: brings out Martian clouds, lunar contrast, Saturn's belts and polar regions, and bright areas on Jupiter.
- Moon filter: reduces the glare of a bright Moon so surface detail is easier to see.
- CPL filter: reduces polarised light to improve contrast on the Moon and planets.


Compatibility and Accessory Notes
- Fits: 1.25″ eyepieces, diagonals and accessories with M28.5 x 0.6 filter threads.
- Stacking: filters can be combined, for example a colour filter with the moon filter.

Good to Know Before You Order
- Visual filters: the set is designed for visual observing; darker filters such as #23A work best with larger apertures, where there is more light to spare.
- 1.25″ only: the cells fit 1.25″ threads, not 2″.
Frequently Asked Questions
Is it difficult to set up?
No. Each filter threads into the bottom of a 1.25″ eyepiece barrel.
Which filter should I start with on Jupiter?
SVBONY suggests orange (#21) for the Great Red Spot and red (#23A) for belt contrast; blue (#82A) brings out the brighter zones.
Can I use the moon filter with a colour filter?
Yes. The cells are threaded on both sides for stacking.
Bottom Line
In short: seven threaded 1.25″ filters — five planetary colours, a moon filter and a CPL — that give you a contrast tool for each of the bright planets and the Moon.
