The Moon&SkyGlow filter is a multi-purpose tool:
- slightly reduces the effect of light pollution from cities and the moon, making deep sky objects appear more contrasty.
- Also useful for planetary observation: its pale bluish glass material brightens the cloud bands of Jupiter or the polar cap of Mars.
- Customer feedback suggests that it is also useful for daytime observation: it noticeably increases the contrast of the landscape, making the field of view "clearer".
