Sky & Telescope called it a Hot Product. Years of owner reviews later, the AT60ED has earned that reputation many times over. This is a 60mm f/6 ED doublet with FPL-53 and Lanthanum glass — the same premium ED optics that define refractor performance — packed into a scope small enough to fit a backpack. It works as a wide-field visual scope, a capable travel refractor, a guide scope, or a small-chip astrophotography platform. It does all four well, and none of them compromise.
The key is the glass. FPL-53 is Ohara's premium ED element, paired here with a Lanthanum element to deliver virtually zero chromatic aberration at f/6. The AT60ED's 360mm focal length is fast — fast enough for efficient wide-field imaging, fast enough to show brighter deep-sky objects in impressive fields of view, fast enough that you can gather a surprising amount of light in short exposures. For a scope you can literally carry in one hand, that's serious capability.
The focuser is a dual-speed 2-inch Rack and Pinion with 10:1 fine focus and a camera angle adjuster. This is the kind of focuser found on much larger scopes. The CAA lets you rotate your camera or guide camera for framing without moving focus. The scope mounts via a finder ring with a 1/4"-20 tapped foot — straight onto a photo tripod, or into a standard finder shoe on a larger scope for piggyback work. The retractable dew shield stores flat against the tube for travel. Light, compact, versatile, and with optics that punch far above the aperture.
The Optical Design
FPL-53 glass is Ohara's premium ED element. Paired with a Lanthanum element, it produces a doublet design that delivers near-zero chromatic aberration at this focal ratio. The surfaces are fully multicoated to maximize light transmission and contrast. What this means in practice: bright, sharp star images with virtually no false color, even at moderate magnifications. The 360mm focal length at f/6 puts the AT60ED in the sweet spot where refractors excel — fast enough to be practical, slow enough to be forgiving on eyepiece quality.
The Focuser
Most 60mm scopes come with a simple focuser. The AT60ED doesn't. The 2-inch dual-speed Rack and Pinion gives you coarse focus on one knob and 10:1 fine focus on a concentric microknob. For visual work at moderate powers, coarse focus is fine. For astrophotography with a camera that weighs more than an eyepiece, or when you're chasing critical focus on a guide star, the 10:1 ratio becomes essential. One user loaded a 2" diagonal, a wide-field eyepiece, and a camera onto the drawtube — over 3 pounds — and reported the focuser held position without drift.
The built-in camera angle adjuster lets you rotate your camera or guide camera for framing without disturbing focus. Loosen the adjuster, rotate to your desired angle, tighten. For astrophotography, this saves you from the usual dance of adjusting focus after rotating the camera. For guide scope work, it means you can position your guide camera to find a suitable guide star without refocusing.
Built for the Field
This scope was designed for motion — from the car to the dark site, from the backyard to a high-altitude location, from sitting on a photo tripod to riding piggyback on a larger scope. The finder ring with 1/4"-20 tapped foot is the key. Any photo tripod, any finder shoe, any mounting bracket with standard photo threads accepts it. No special adapters, no dovetails that only fit one brand of mount, no compromise with existing gear.
At about 3.25 pounds, the AT60ED is among the lightest refractors in the Astro-Tech lineup — light enough to carry in one hand, ride piggyback on a larger scope, or sit on a sturdy photo tripod. For travel, for driveway astronomy, for throw-it-in-the-car observing, weight matters. This scope goes everywhere.
The guide scope role is worth its own mention. At 360mm focal length, the AT60ED provides enough image scale for reliable autoguiding with standard guide cameras. The camera angle adjuster means you can position your guide camera without refocusing. Mount it on a finder shoe above your main imaging rig, and you have a compact, capable guide scope that doesn't consume real estate or add weight to your imaging setup. For small to mid-size refractors, the AT60ED serves double duty: when you upgrade to a larger imaging scope, keep it as your guide scope.
The 1/4"-20 mount also accepts standard photo tripod heads — ball heads, geared heads, whatever you prefer. Attach it to a quality photo tripod and you have a wide-field visual scope that sets up in seconds and fits in the car without contention for space.

Under the Night Sky
The Moon through a 60mm f/6 refractor is a masterclass in what aperture isn't everything. At 60x with a 6mm eyepiece, the Moon fills the field and the terminator comes alive with shadow detail — crater walls catching the first light, rilles threading across mare floors. The bright craters pop against the dark maria with the contrast that only a well-corrected refractor delivers. At 100x on steady nights, you're seeing sharp, high-contrast lunar features. It's not a 10-inch Dob, but what you see is vivid and real.
Jupiter and Saturn reward the AT60ED with surprisingly detailed views. Jupiter reveals the two main equatorial belts and the changing positions of its Galilean moons. Saturn shows its ring system clearly separated from the globe, and under steady skies hints of the Cassini Division become visible. The Moon is especially rewarding, with razor-sharp crater walls and excellent contrast along the terminator. You won't achieve planetary mag-140x performance, but the AT60ED at 100-120x delivers planetary views that make you forget you're looking at a 60mm scope.
Double stars are a refractor speciality, and the AT60ED shows them well. Albireo splits easily even at low power, gold and blue separated cleanly. Epsilon Lyrae — the Double Double — resolves all four components at 100x. The contrast and sharpness are what refractors are actually for, and the AT60ED doesn't disappoint.
Wide-field deep-sky is where the AT60ED shines. At f/6 with 360mm focal length, a 30mm eyepiece delivers a 3-degree field of view — large enough that you're seeing context, seeing neighborhoods of stars, seeing the Milky Way as a structure rather than scattered points. The Pleiades fill the field with their brightness and arrangement. The Double Cluster in Perseus spans the view with a clarity that only a refractor delivers. The Andromeda Galaxy stretches across the field at low power with dark lanes visible on a good night. M31, M33, the Hyades, the Beehive — all look better through a 60mm f/6 than through higher-magnification instruments. Wide-field observing rewards aperture and focal ratio over magnification, and the AT60ED has both.
Planets are limited by aperture — you won't resolve detail on Mars or Saturn that a 6-inch scope shows. Faint galaxies are out of reach. The dimmest planetary nebulae are inaccessible. But everything bright, everything colorful, everything that benefits from pure optical excellence and wide fields of view is fair game. Use the AT60ED for what it's built for, and it delivers.
Community Says
The AT60ED has been discussed and dissected on Cloudy Nights for years, often head-to-head against pricier rivals. The recurring verdict from owners is that the optics punch well above the price.
"Nice focuser, fit/finish, and performance for the price!... I bought it as a travel AP scope."
— Cloudy Nights AT60ED imaging discussion. This owner pairs it with the matching 1× field flattener and camera angle adjuster on a travel mount.
Owners consistently place its optics in the same conversation as refractors costing considerably more — which, for a scope this small and this affordable, is the whole point.
Observing Tip
The AT60ED excels in wide-field observing, and wide-field observing rewards low power and large exit pupils. A 30mm eyepiece at 12x, a 25mm at 14x, a 20mm at 18x — these are the magnifications where the AT60ED sings. The 360mm focal length and f/6 ratio were designed for exactly this kind of use. Pair it with a quality 30-35mm eyepiece and you have a device for exploring the Milky Way that rewires how you think about observing.
Frequently Asked Questions
How does the AT60ED compare to the AT72EDII?
Same glass family (both FPL-53 + Lanthanum), same f/6 focal ratio, same camera angle adjuster. The AT72EDII has more aperture — 72mm vs. 60mm — which means 44% more light, higher resolution, and slightly more reach at 432mm vs. 360mm focal length. The AT72EDII comes with two tube rings and a Vixen dovetail (heavier, more capable mounting). The AT60ED uses a simple 1/4"-20 foot (lighter, more flexible mounting). Choose the AT60ED for maximum portability and versatility; choose the AT72EDII for more aperture in a still-compact package.
What's the difference between FPL-53 and FK-61 glass?
FPL-53 is Ohara's premium ED element; FK-61 is Schott's FPL-51 equivalent (also excellent, but a different standard). FPL-53 generally allows tighter color correction than FK-61 when used in similar optical designs. The AT60ED uses FPL-53. The AT70ED uses FK-61 with a simpler focuser and no CAA. Both are good scopes; the AT60ED is the premium version.
Can I use this as a guide scope?
Yes — it's an ideal guide scope. At 360mm focal length, the AT60ED provides enough image scale for reliable autoguiding with standard guide cameras. The 10:1 fine-focus ratio makes guide star acquisition precise. The camera angle adjuster lets you rotate your guide camera to find a guide star without refocusing. Mount it on a finder shoe above your main imaging rig and it will serve you for years.
Is this good for astrophotography?
Yes, for wide-field deep-sky imaging. At 360mm f/6, the AT60ED frames large open clusters, nebulae, and galaxies efficiently. Pair it with the ATRF60 0.8× reducer for 288mm at f/4.8 (faster, wider field). Pair it with the AT60FF 1× field flattener for full focal length imaging at f/6 with flat stars to the corners. The camera angle adjuster makes framing straightforward. For small-chip or crop-sensor cameras, the AT60ED is a capable wide-field imaging platform.
What mount or tripod do I need?
For visual observing, the AT60ED works well on a sturdy photographic tripod or lightweight alt-azimuth mount. For astrophotography, a small equatorial mount such as an HEQ5, AM3, or similar class mount provides more than enough capacity. You will need a Vixen Dovetail to attach the AT60ED to a telescope mount.
What else do I need to start observing?
The scope is OTA only — no mount, eyepieces, diagonal, or finder are included. For visual observing, budget for a 2" star diagonal, a set of eyepieces (a 30mm for wide-field, a 12-15mm for medium power, and a 6-8mm for higher magnification is a good starting set), and a finderscope or red dot sight. If you're new to refractors, invest in quality accessories. A scope this good deserves eyepieces and a diagonal that match its optics.

Final Thoughts
The AT60ED is the smallest Astro-Tech refractor with FPL-53 glass, and it pulls off something rare: maximum versatility without compromise. Premium optics, a 2-inch focuser with camera angle adjuster, a simple 1/4"-20 mount that works with anything, and a form factor so compact you forget you're carrying it. Guide scope, travel refractor, wide-field imager, or grab-and-go visual telescope — few scopes at any price fill as many roles as effectively as the AT60ED. Years of owner reviews and a Sky & Telescope Hot Product award don't come from hype. They come from a scope that actually delivers what its specs promise, and then some.
