Telescopes & Astronomy

• Enhance your 8” Rowe-Ackermann Schmidt Astrograph (RASA) by blocking light pollution, improving image contrast, and darkening the sky background.
• This filter selectively blocks wavelengths of light from sources of light pollution, such as streetlights, not broad regions of the spectrum.
• Does not block wavelengths associated with emission nebulae, keeping your nebula images bright and detailed.
• Fits into the 8” RASA’s integrated filter mount, maintaining peak optical performance.
• Optically flat surfaces free of defects, constructed of Schott glass with anti-reflection coatings.

Bring out the best in your nebulae astroimages with the H-alpha H-beta OIII (Hα-Hβ-OIII) Imaging Filter for the 8” RASA. This specialized filter allows high transmission of light from emission nebulae while blocking light pollution, helping to make your images pop with detail off the black sky background with superior contrast.

Fortunately, many sources of light pollution have relatively discreet emission spectra; they emit primarily at specific wavelengths of light. By strategically blocking these “bad” wavelengths, the filter essentially eliminates the effect of light pollution while letting the “good” wavelengths of light associated with the emission nebula pass through to the camera. You’ll notice much higher contrast in your images immediately, even if imaging from your light polluted backyard! And since the transmission at the key wavelengths is so high, the nebula will not be dimmed—only the background will be blacker.

The Advanced VX (AVX) sets a standard in mid-level telescopes, providing many of the features found on Celestron’s most sophisticated German equatorial mounts at an extremely affordable price.

The Advanced VX 8” Newtonian telescope is an excellent entry- to mid-level setup that can grow with you. The Newtonian optical design is excellent for visual observing and offers you the largest aperture for the price. The parabolic primary mirror minimizes spherical aberration to produce a sharper image near the edge of the field of view. The 8” Newtonian optical tube offers 78% more light gathering ability than the 6” Newtonian optical tube.

The Advanced VX mount is designed to provide superior performance for smaller telescopes while taking advantage of Celestron’s most advanced technologies: All-Star Polar Alignment, Celestron PWI telescope control software, and permanently programmable periodic error correction (PPEC).

If you’re an experienced imager, you’ll love taking this portable mount to a dark sky site and enjoying all the conveniences of a larger observatory mount. Or, if you’re new to imaging, Advanced VX will help you get started with the hobby and keep up with your needs for years to come.

• 6” (150mm) f/5 optical design gives excellent wide field views
