Astrophotography

• 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 HEQ5 GOTO mounts are the perfect entry level computerised GOTO mount for beginners as well as experienced astronomers. The HEQ5 provides extremely high precision tracking and have built in autoguider ports.

This heavy-duty HEQ5 Pro mount has a maximun rated payload capcity of 13.7 kg and is a smaller version of the venerable and sturdy EQ6 Pro and NEQ6 Pro mounts. The HEQ5 Pro is specially designed for observers wanting to step into astro imaging but may find the EQ6 mounts a bit too heavy. 

The HEQ5 pro comes with a 3 year limited warranty.
