Telescopes & Astronomy

Turn your Celestron PowerSeeker telescope into a solar scope! The EclipSmart Eclipse Solar Filter is a must-have accessory perfect for viewing the Sun and eclipses. Affordable, easy to use, and best of all, all Celestron EclipSmart products conform to the ISO 12312-2:2015(E) international safety standard.

• 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.

A must have accessory for lunar observing. Standard filter threads screw onto 2in eyepieces.

Polarising filters can be used to increase contrast in some images, and can be especially useful for daytime photography.

• For use with 1.25” eyepieces.
• One of the essential eyepiece filters for visual astronomy.
• Reduce glare from bright objects such as the Moon, Venus, and Jupiter.
• Accentuate subtle detail for the Moon and planets
• Polar ice caps of Mars in large telescopes
• Limb hazes and terminator clouds of Mars
