Optimize your astrophotography with the Celestron Light Pollution Imaging Filter designed for the 8” Rowe-Ackermann Schmidt Astrograph (RASA). This filter is a crucial tool for enhancing image contrast and reducing light pollution effects, particularly useful in urban environments where streetlights and other artificial sources can impede the clarity of celestial images. By selectively blocking specific wavelengths of light from common sources of light pollution, this filter ensures that the natural beauty of emission nebulae remains bright and detailed in your images.

The filter is engineered to fit seamlessly into the 8” RASA's integrated filter mount, ensuring that the telescope's optimal optical performance is retained. Constructed from high-quality Schott glass and featuring anti-reflection coatings, this filter boasts optically flat surfaces, free from defects, guaranteeing superior image quality.

When using fast telescopes like the 8” RASA, the saturation of the sky background can be a significant issue due to light pollution. This filter addresses this problem by effectively blocking unwanted light, thereby enhancing the contrast between the celestial object and the background sky. This results in celestial objects that stand out with greater clarity and detail against a darker sky background.

The Light Pollution Imaging Filter for the 8” RASA targets the most prevalent sources of light pollution in the visible spectrum (400-700nm), including sodium-vapor and mercury-vapor streetlights, as well as natural atmospheric airglow. Its design is focused on blocking specific areas of the spectrum rather than broad regions, maintaining the brightness and color balance of your images. Crucially, it allows for high transmission of specific wavelengths associated with emission nebulae, ensuring that these objects remain vivid and detailed in your observations.

This filter integrates directly into the RASA 8's front lens cell, replacing the standard optical window. This placement ensures that the overall optical performance of the system is maintained while adding the benefit of light pollution reduction.

Each Celestron Light Pollution Imaging Filter comes with a durable plastic storage case for safekeeping. Additionally, you'll receive a unique spectral transmission graph for your specific filter, providing assurance of its performance and effectiveness in enhancing your astrophotography experiences.
