Reveal celestial wonders like the desolate beauty of the lunar terrain, the serene structure of Saturn’s rings or the brightest deep sky treasures of the Messier catalog with Explore Scientific’s 80mm FCD100 Apochromatic Refractor.

This is essentially the same scope as the ES-ED0806-01 but offering greater quality optics. We use Hoya FCD100 optics which is very similar in characteristics as Ohara FPL-53. Having a true diffraction-limited optical design and sized to encourage spontaneous stargazing sessions, this high-quality telescope is a perfect grab-and-go instrument for exploring the skies.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD100 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

In addition, this amazing little scope also includes a 2.5" Hexagonal focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser. 

Although it is a standout telescope on its own, the 80mm also is compact enough to mount on a larger telescope, which can add versatility to your astrophotography experience by separating the guiding and imaging duties.

I wanted to clarify my rationale for my recent telescope purchase:

Normally I try to buy everything from Jeff Norwood at Camera Concepts and Telescope Solutions. But Woodland Hills (Telescopes.net) had an "open box" ES 80mm Essential APO Triplet for $589. I needed a scope for the eclipse, so I went for it. It was still way over budget for me, but I figured a deal like that wasn't going to come again between now and August.

But they were "sold out", but promised me another, at the same price. About 2 months later I finally got it. But it had some Chromatic Aberration (CA). It was not terrible, and I should have just kept my mouth shut, but I complained to Woodland Hills and Explore Scientific about it. So then they somehow convinced me to return that scope and give them another $410 for their higher-end version of the same scope, the FCD-100 80mm APO, with Hoya glass, claiming virtual CA free performance. I guess it was a "weak moment". Well that was another 2 months ago, And Explore Scientific, every week, tells me it is "shipping this Friday". So now I am done with both Woodland Hills and Explore Scientific. I am now fighting to get my money back. They won't return my E-mails or phone calls. Lesson learned: Always buy from Jeff!

I am very happy with this $265, 90mm Achromat, and it will serve me well for the eclipse, and maybe even some deep sky work. That was exactly what I was looking to spend to capture the eclipse (I really just want the corona, if I am lucky enough to see it at all).

Even yesterday's First Light, which was really just a test of the scope with various reducers and flatteners (all from Jeff!), with a giant moon right next to where I was imaging, and big winds, was impressive. With minimal processing (I easily removed the "purple haze" around the bright stars using PhotoShop - sorry Jimi Hendricks).

This is a single 30 second exposure of M37, no darks, flats or bias frames, and slightly copped from 4272 x 2848 pixels to 3600 x 2400 pixels, using my older and trustworthy, $399 Canon EOS T3 without any filters.
