Celestron Light Pollution Imaging Filter for 11 RASA

Celestron Light Pollution Imaging Filter for 11 RASA

Maximize the capabilities of your Celestron Rowe-Ackermann Schmidt Astrograph 11 with the custom-designed Light Pollution Imaging Filter. Even in urban areas, capture the night sky's wonders without the interference of artificial light.

Selective Light Filtering:

This filter adeptly blocks intrusive wavelengths from streetlights and other common sources of light pollution. It uniquely maintains over 90% of the telescope's light capturing ability across many wavelengths, ensuring bright images without the typical color imbalances—no more overly green or blue tints.

Neutral Color Balance:

Designed to provide a neutral color balance, it allows for capturing the subtle hues in galaxies and deep-sky objects. The multiple dielectric coatings are engineered for the desired transmission, while anti-reflective layers reduce star halos and reflections.

Quality and Protection:

Each filter is individually tested for light transmission, and you receive a transmission spectrum graph for your filter. With its machined aluminum housing and durable Schott B270 glass, the filter is also safeguarded by a clear plastic case when not in use.

Specifications:

-Glass Thickness: 2.1mm

-Clear Aperture: 68mm

-Coatings: Hard coated dielectric and multi-layer anti-reflection

-Housing: Anodized aluminum.
