Askar 60F Quadruplet Refractor Review: A Full-Frame Astrograph For Under $500
Six months of nights under the stars with a 60mm quadruplet that punches way above its price tag.
1. First Look & Verdict
The Askar 60F Quadruplet Refractor is the little scope I keep grabbing when I only have 90 minutes of clear sky. It costs about $499, weighs less than a bag of flour, and gives full-frame sensors flat, tight star fields right out of the tube. If you want one small scope that can shoot big nebulae and still fit on a light star tracker, this is my top pick for 2026 in the entry APO class.
I write about small imaging refractors for a living. Since 2019 I have shot with more than 20 different astrographs, from the Redcat 51 to the FRA400. I got my Askar 60F in January 2026 and have logged 47 nights with it as of July. That includes backyard sessions in a red-zone city, two trips to a Bortle 3 dark site, and a wildfire-smoke week where I stress-tested the focuser.

What’s in the Box
- 60F OTA (dew shield retracted)
- Pair of tube rings + carry handle
- 230 mm Vixen-style dovetail plate
- Two finder shoe bases
- Photographic extension tube with 2″ filter thread
- M48 and M54 adapters
- Metal soft case with foam cutouts
3. Design & Build Quality
The 60F wears a matte white finish with orange trim. The paint is thick, even, and did not chip when I dropped a lens cap on it (please do not test this on purpose). The rings clamp firmly and never slipped, even with a 700 g camera hanging off the back.
Focuser Feel
The 2.4″ rack-and-pinion focuser is the star of the show. It moved a full ZWO ASI2600MC Duo, a filter wheel, and an OAG (about 1.4 kg total) with zero sag. The 1:10 fine knob has real bite — you can nail focus in one nudge. I measured under 5 microns of slop with a dial indicator, which is honestly wild at this price.
Portability
At around 2.5 kg with rings and dovetail, the 60F rides fine on a Star Adventurer GTi or an AM3. I fit the full kit plus a small mount into a backpack on my Bortle 3 trip. That is the whole point of a scope like this.
4. Performance Analysis
4.1 Core Astrophotography Performance
I ran the 60F on an ASI2600MC Duo (APS-C) and a full-frame Nikon Z6. Native focal length gives 408 mm, so the field is wide enough for the North America Nebula but tight enough for the Andromeda core. Star tests showed:
- APS-C corners: round stars all the way out, average eccentricity 0.42.
- Full frame corners: mild elongation without the reducer, but drop in the 0.75x reducer and it cleans up to under 0.5 eccentricity.
- Chromatic aberration: I could not spot any blue or purple halos around Vega, even at 400% zoom.
The Space Koala’s real-world Askar 60F test at f/6.8 lines up with what I saw in my own data.
4.2 Key Performance Categories
Star Sharpness: Center FWHM sat between 2.1 and 2.4 arcsec on nights with 2.5″ seeing. That is as tight as the atmosphere lets a 60 mm scope go. The stars stay round in every corner on APS-C.
Field Flatness: The 44 mm image circle is not a marketing number. I checked corner stars on my Z6 with 60-second subs. Native focal length leaves a tiny bit of tilt in the far corners of full-frame sensors, mostly cleared with a shim. Add the 60F 0.75x reducer for a truly flat 44 mm circle at 306 mm f/5.1.
Color Correction: ED glass plus the four-element design pulls all three color channels to the same focus point. My star profile plots showed less than 1 pixel of red-vs-blue focus drift. That is better than most doublets and on par with the pricier Askar 71F Flat Field Quadruplet APO Refractor.
5. User Experience
Setup takes me under six minutes from bag to first sub-frame. Screw the dovetail into your saddle, thread the camera into the M48 or M54 port, dial back-focus to 55 mm, and you are shooting. There is no complex flattener spacing chart to fight.
Daily Use Story
My favorite night with the 60F was March 14, 2026. I had a two-hour gap between clouds. I framed up M81 and M82, ran ten one-minute subs, and stacked in PixInsight before bed. That would not have been worth the effort with my heavier 130 mm triplet. Small scopes get used more. That is the whole point.

New to astrophotography? The 60F is beginner friendly. Nothing to align, no flattener spacing math for APS-C, no strange back-focus tricks. If you can screw a camera onto an adapter, you are ready.
6. How It Stacks Up (Askar 60F vs Rivals)
Buyers cross-shop the 60F with the Askar 71F Quadruplet, the FRA300, and the Redcat 51. Here is where each one lands.
| Model | Aperture | Focal Length | f-ratio | Weight | Image Circle | Price (2026) |
|---|---|---|---|---|---|---|
| Askar 60F | 60 mm | 408 mm | f/6.8 | 2.5 kg | 44 mm | $499 |
| Askar 71F Flat Field | 71 mm | 490 mm | f/6.9 | 3.1 kg | 44 mm | $659 |
| Askar FRA300 60mm f/5 | 60 mm | 300 mm | f/5 | 2.4 kg | 44 mm | $799 |
| William Optics Redcat 51 II | 51 mm | 250 mm | f/4.9 | 1.9 kg | 44 mm | $798 |
| Askar V (60mm mode) | 60 mm | 360 mm | f/6 | 2.3 kg | 44 mm | $898 |
Askar 60F vs Askar 71F Quadruplet: The 71F gathers about 40% more light and gives a longer focal length. It is the better pick if your targets are galaxies or planetary nebulae. The 60F wins on price, weight, and wide-field framing. If you already own the 71F, the 60F still makes sense as a lighter travel scope.
Askar 60F vs FRA400 72mm f/5.6 Quintuplet APO Astrograph: The FRA400 is a five-element Petzval with better native flatness and a shorter focal ratio. It also costs almost twice as much. If you shoot from a fixed backyard rig, the FRA400 is sharper wide open. If you carry your scope in a bag, the 60F wins.
Unique selling point: No other 60 mm scope in 2026 gives you a real 44 mm flat image circle, a 1:10 rack-and-pinion focuser, and a full accessory kit for $499.
7. Pros & Cons
What I Loved
- Sharp corner stars on APS-C right out of the box
- Big, buttery-smooth 2.4″ rack-and-pinion focuser
- Real 44 mm image circle for full-frame shooters
- Zero visible chromatic aberration on bright stars
- Built-in 2″ filter thread saves buying a nosepiece
- Light enough for the Star Adventurer GTi and AM3
- $499 price undercuts every other quadruplet APO
Room for Improvement
- Full-frame corners need the extra 0.75x reducer ($199)
- Dew shield could be a bit longer for humid nights
- No included Bahtinov mask
- Soft case is only okay, not padded like the 71F case
- Focuser has no motor mount pattern for the ZWO EAF (need adapter)
8. Evolution & Updates (2026)
The 60F is a newer sibling to the loved Askar 71F Flat Field ED Refractor. Askar borrowed the same self-flattening quadruplet design, then shrank the glass and dropped the price. The 2026 batch (serial numbers 60F-26xxx) ships with an updated focuser knob that has knurled grip rings — a real upgrade from the 2025 first-run knobs that could feel slick with gloves on.
Askar also released a matched Askar 0.75x reducer for the 60F in early 2026. It sells for $199 and turns the scope into a 306 mm f/5.1 astrograph. Third-party flatteners are not needed and not recommended, since the 60F is already flattened.
9. Buying Advice
Best For
- Beginner astrophotographers who want one scope that just works
- Travel imagers who need something under 3 kg
- Owners of light star trackers (Star Adventurer GTi, AM3, HAE29)
- APS-C shooters who plan to keep their camera long term
- DSO fans framing wide targets like the Heart Nebula, Rosette, or Andromeda
Skip It If
- You image mostly small galaxies (get the Askar 103 APO Triplet Refractor or a longer scope)
- You want the shortest, fastest system possible (look at the Redcat 51 or FRA300)
- You need a modular scope that grows with you (the Askar V is a better fit)
Alternatives to Consider
If your budget stretches to $650, the Askar 71F Flat Field Quadruplet APO Refractor is a step up in aperture. If you want a Petzval with a shorter focal length, the Askar FRA400 72mm f/5.6 Quintuplet APO Astrograph is worth the extra spend. On the deep-galaxy end, the Askar 103 APO Triplet Refractor is a fine choice for anyone with a bigger mount.

Editor’s Choice — Best Sub-$500 Full-Frame Astrograph, 2026
The Askar 60F Quadruplet Refractor is the small scope I recommend to almost every new imager in 2026. It is sharp, well built, and truly full-frame ready when paired with its own reducer. For $499, nothing else in the class comes close.
Bottom line: If you want a first serious astrograph, a travel scope, or a light second rig, buy the 60F without a second thought. The only reason to skip it is if you already own the 71F and shoot mostly galaxies.

Long-Term Update — July 2026
After 47 nights and roughly 90 hours of integration time, the focuser is still tight, the paint is still clean, and I have not had to send it back for anything. The only real change: I added a Bahtinov mask and a light dew heater. The scope itself has not needed a single tweak.
