The ATIK LRGB 36mm set consists of Luminance, Red, Green and blue filters, that have been designed for CCD cameras to image deep sky objects, galaxies and stars in their natural colour. Take advantage of our special offer. Get 50% off any filter set (or both filter sets), when you buy any Atik mono camera (with the exception of the Atik GP).

If a natural colour representation is what you want from you deep-sky imaging, an LRGB filter set should be your first choice. With OIII emission overlapping on the blue and green filters to allow high efficiency and natural colour imaging of all deep-sky objects. The gap between green and red filters serves to block out the light pollution line at 589nm and improves the colour of your images.

Get the most out of your Celestron Rowe-Ackermann Schmidt Astrograph 11, even under light-polluted skies, with this Light Pollution Imaging Filter, custom-designed for the RASA. No matter which camera you use, this filter’s generous 68 mm clear aperture allows it to easily accommodate today’s largest sensors. Utilizing a machined aluminum housing and Schott B270 glass, the filter replaces the RASA’s clear optical window so the RASA’s optical performance is unaltered.

Remove Light Pollution While Keeping Your Images Bright
Light pollution limits how much of the night sky we can see and photograph. When imaging with a color camera in light polluted areas, skyglow degrades image quality. Light pollution filters help to selectively block light emitted from common streetlights and other ambient lighting. But most light pollution filters greatly compromise the total light throughput, causing dim images, and negatively impact the color balance, causing images to appear too green or blue.

The Light Pollution Imaging Filter for RASA “surgically” removes unwanted light pollution while preserving as much of the useful spectrum as possible. That means you’ll still retain over 90 percent of the light captured by your telescope at many wavelengths.

Unlike other light pollution suppression filters, the Celestron LP Imaging Filter for RASA maintains a relatively neutral color balance so you can bring out subtle color in galaxies and other faint deep sky objects. Multiple layers of specially-formulated dielectric coatings provide the desired transmission, while anti-reflective coatings minimize star halos and internal reflections.

Also included is a clear plastic case to protect the filter when not in use

Individually Tested for Quality
Every RASA 11 Light Pollution Imaging Filter is tested individually for light transmission. Inside the box, you’ll receive a graph detailing the actual transmission spectrum for your specific filter.
