The Moon filter greatly increases contrast when observing the Moon. Harsh moonlight is softened so that structures can be more easily identified. This can also provide better separation of components when observing binary stars if they have considerably different magnitudes.
This set offers you
- three Moon filters with varying degrees of transparency: 13%, 25% and 50% transmittance. This means that you can find the optimum magnitude.
- a Sky Glow filter for improved visibility of deep sky objects in light-polluted skies.
The set comes in a sturdy plastic case with an integrated lunar map.
