Surface details on Jupiter and Mars become more intense. If you never saw the Great Red Spot on Jupiter before - now you will have success! |

Ultimative moon filter - the moon and the sun appear more naturally as with classical green moon filters (often delivered with cheap beginner telescopes). Disturbing glare is removed. You never saw the moon and the sun (with appropriate solar filter!) that sharp in a beginner telescope! |

Blocks disturbing atmospherical straylight (Skyglow). The skies background becomes black. |

Fits into all standard filter threads. For instance, it can be combined with the Baader IR cut filter. Now, unsharp pictures by unfocused Infra red radiation is prevented - a must for digital photography! |
