EON 80mm ED Apochromatic Refractor
Code:- 9927

Fast f/6.25 optics and all-machined, premium mechanics make for an awesome imaging telescope.
80mm doublet lens crafted with FPL-53 "ED" glass to virtually eliminate chromatic aberration.
Machined aluminum 2" Crayford focuser has dual-speed focus knobs with 11:1 fine-focus ratio.
23% more light grasp than the EON 72ED, yet at 15.5" long is still extremely portable.
Retractable lens shade, dovetail mounting bar, finder scope base, and carrying case included.

The EON 80ED is really an imager's dream scope. The 500mm focal length yields an f-ratio of 6.25, faster than the standard ED80, which is f/7.5. So the EON 80ED gives you brighter images, a wider field of view, and allows shorter exposures of deep-sky objects. The 80mm air-spaced doublet lens is crafted with one element of FPL-53 extra-low dispersion, "ED", optical glass, which virtually eliminates the effects of chromatic aberration. All air-to-glass lens surfaces are fully multi-coated for maximum light throughput. Baffles inside the optical tube, glare threads in the focuser drawtube, and a retracting lens shade/dew shield eliminate unwanted glare to deliver crisp, high-contrast images. And the EON 80ED brings 23% more light grasp to the task than the EON 72ED, yet at 15.5" with the lens shade retracted is only 3" longer, so still extremely portable.

EON 120mm ED Apochromatic Refractor
Code:- 9925

A breakthrough in performance and value, our biggest EON will delight the avid observer or imager.
120mm doublet lens crafted with FPL-53 "ED" glass to virtually eliminate chromatic aberration.
Focal length of 900mm (f/7.5) provides excellent magnification and resolving power.
Machined aluminum 2" Crayford focuser has dual-speed focus knobs with 11:1 fine-focus ratio.
Retractable lens shade, tube rings and mounting plate, finder scope base, carrying case included.

The EON 120ED's optics consist of a fully multi-coated, air-spaced 120mm objective doublet lens of exceptional quality, containing one element of FPL-53 extra-low dispersion — "ED" — optical glass. The ED glass virtually eliminates the color fringing around bright objects resulting from chromatic aberration. Images are crisp, sharp, and color-pure, even at magnifications upwards of 250x. The big 120mm objective has a 900mm focal length (f/7.5), a combination that provides excellent high-contrast resolving power, with enough magnification to home in on smaller targets. Baffles inside the optical tube, glare threads in the focuser drawtube, and a retracting lens shade/dew shield eliminate unwanted glare.

Finally, A Premium "Apo" You Can Actually Afford
We love those premium "apo" refractors as much as the next guy. We just don't think you should have to work a second job or put the family heirlooms on eBay to own one. Now you won't, thanks to our amazingly affordable 80mm ED refractor.

Its fully multi-coated 80mm objective doublet contains one element crafted from extra-low-dispersion FPL-53 glass. Images are virtually free of chromatic aberration! With a focal length of 600mm (f/7.5), the "ED80" is wonderfully suited for visual applications on both solar system and deep-sky objects as well as for prime-focus astrophotography and CCD imaging.

*Sold as optical tube assembly only*, without accessories. Finished in gunmetal gray metallic enamel. Compatible tube rings are #7371, sold separately. One-year limited warranty.

Orion 100mm ED Apochromatic Refractor OTA
Code:- 9975

The "ED100" delivers images remarkably free of chromatic aberration, thanks to its fully multi-coated 100mm objective doublet. It's crafted with one element of FPL-53 extra-low dispersion "ED" optical glass from Japan. The 100mm aperture gives it 56% greater light grasp than our ED80. And the 900mm focal length (f/9.0) is ideal for visual planetary and lunar study and excels for imaging work as well.

Join the revolution in affordable apochromatic refractors. You'll save big and still enjoy the amazing image quality that only an apochromatic refractor can produce.
