Celestron Astro-Fi 130 Review – Recommended Scope

Celestron’s Astro-Fi 130 is part of the company’s latest attempts to make GoTo telescopes and stargazing as accessible as possible to newbie stargazers, and completely succeeds with only a few minor drawbacks.

Celestron introduced the Astro-Fi line of telescopes relatively recently, and it is such an improvement over their old SLT telescopes (which the Astro-Fi heavily draws from technologically) that I don’t understand why the SLTs haven’t just been discontinued altogether. The Astro-Fi telescopes, along with Celestron’s NexStar Evolution line, are some of the only telescopes on the market with built-in WiFi connection and designed to be controlled with a phone or tablet. This finally brings computerized telescope technology into the 21st century and allows you to forego the confusing, outdated, and quite frankly unintuitive LCD hand controllers that most computerized telescopes still possess.

Astro Fi 130 provides enough aperture to see a fair amount of things in the night sky (properly leveraging the capabilities of the GoTo technology), a wide field of view to fit even the largest deep-sky objects, and it doesn’t significantly strain the relatively lightweight Astro-Fi mount.

Bottom Line

While a Dobsonian will provide you with somewhat better views and doesn’t require power or alignment, the Celestron Astro-Fi 130 takes all of the stress and confusion out of a GoTo telescope and provides enough aperture to get you started with stargazing.

The Optical Tube & Capabilities Of Astro Fi 130

The Astro-Fi 130’s optical tube is identical to most 130mm f/5 Newtonians on the market. These all tend to have good optics, and the 5.1” of aperture is enough to begin delving into serious deep-sky observation as well as lunar and planetary viewing. The f/5 focal ratio also enables a relatively wide field of view: 2.1 degrees (over 4 full moons across) with the included 25mm Kellner eyepiece, over 2.5 degrees with the widest-field 1.25” eyepiece, and up to about 3.5 degrees if you can adapt a 2” eyepiece to it.

With good collimation and air seeing conditions, the Celestron Astro Fi 130 can handle magnifications up to 260x, though you’ll probably want to use less than that on everything except perhaps the tightest double stars on the best of nights.

The noticeable difference of the Astro-Fi 130 compared to many other 130mm Newtonians is its 2.5” rack-and-pinion focuser, which it only shares with Celestron’s other 130mm computerised telescopes – Celestron’s NexStar 130SLT and SkyProdigy 130. This focuser is a little confusing – it is technically capable of fitting a 2” eyepiece, but Celestron doesn’t seem to always supply an adapter to make this possible – one 130 I received had one while the other did not. When I called Celestron customer support about the lack of the 2” adapter on the latter, they told me they knew of no such part in existence. Thus, if your scope doesn’t come with the aforementioned adapter and you wish to use 2” eyepieces with it, you may need to 3d-print or otherwise manufacture your own adapter to make this possible.

Collimating the Astro-Fi 130 might be a little difficult for a first-time user, especially since the telescope doesn’t include a collimation tool out of the box. We recommend checking out our collimation guide to learn more about this process.

Reviewing the Accessories

The Astro-Fi 130 comes with 25mm (26x) and 10mm (65x) Kellner eyepieces. While they do lack eyeguards and don’t work the greatest at f/5, they’re all-metal in construction and are decent for a sub-£350 telescope. I’d much rather have them than cheap, plastic Plossls. 

Additionally, the Astro-Fi 130 includes a StarPointer red dot finder for aligning the scope, and newer models include a smartphone adapter built into the lens cap. This adapter is rather crude, but it does function better than merely holding your phone to the eyepiece.

About the Astro-Fi Mount

At first glance, the Celestron Astro-Fi mount outwardly resembles Celestron’s NexStar SLT and GT mounts. However, it is a completely different beast.

For one, the gears in the mount head seem to have been improved compared to the NexStar SLT. There is far less backlash compared to most Celestron mounts. Slewing it is dead simple – the only complaint I have is that it takes a bit to move all the way around the sky even at maximum slewing speed.

Lastly, the spreader has completely changed in design, having a shelf (presumably for your phone) and some rubbery gripping substance on it. I find this to be an improvement over the usually useless metal or plastic spreaders provided with many scopes which do nothing besides serve as a slight structural support.

Like many Celestron GoTo telescopes, the Astro-Fi 130 is powered by 8 AA batteries in a small pack attached to the side of the tripod. Powering the Wi-Fi network will drain these faster compared to a regular, controller-operated telescope, so I would definitely recommend using AC power or a rechargeable 12-volt DC power supply.

Using Celestron’s Skyportal App

Connecting to the Astro-Fi with your phone or tablet is relatively simple. First, download the Celestron SkyPortal app or SkySafari, then turn the scope on. Connect your phone or tablet to the telescope’s Wi-Fi network, then open SkyPortal and hit “Connect & Align”. You should be prompted with alignment instructions.

Alignment is a relatively simple 3-star process based on Celestron’s SkyAlign technology. The entire process from start to finish takes about 4 minutes. You can easily set the scope up and be observing within maybe ten minutes, as assembly is tool-free and only requires putting a couple of things together.

However, unlike the unusable, bug-ridden SkyAlign, the Astro-Fi obtains data from your phone/tablet rather than you entering it in for pinpoint accuracy. I have had no alignment failures with this system and find it very reliable, with very precise GoTos. To test the tracking accuracy, I slewed to M13 at 72x – it was perfectly centred of course by the scope – and left for an hour. When I came back, M13 had moved maybe an arc-minute or two at most – that’s a couple times the apparent diameter of Jupiter, no problem for visual use or planetary astrophotography (which is all this scope is capable of anyway).

If you walk out of range of the Astro-Fi’s WiFi network or power off your device, the scope won’t stop tracking or lose alignment – so if your device dies or you need a cup of coffee, it’s no problem.

What can you see with Celestron Astro Fi 130?

The Celestron Astro-Fi 130 is a great deep-sky telescope. Its wide field of view and decent aperture makes it great for viewing open clusters such as M11 and the Pleiades, as well as nebulae such as the Veil, Swan, and Orion Nebula – though the former will require a good UHC or Oxygen-III filter to see. 5 inches of aperture is not, unfortunately, quite enough to fully resolve globular clusters or show you a ton of galaxies, but you still may be surprised by what the scope can do – particularly on the brighter globular clusters such as M13 and M15 and the springtime galaxies such as the Leo Triplet and Virgo Cluster galaxies – and especially, of course, under dark skies.

The 130 is also a solid instrument for viewing the moon and planets. You’ll be able to see craters just a couple of miles across on the Moon, as well as the phases of Venus and Mercury, the cloud belts and Great Red Spot of Jupiter, and of course its four largest moons. Saturn’s rings, the Cassini Division within them, some faint cloud banding, and a few of its moons are also easy targets for the Astro-Fi 130. Unfortunately, Uranus and Neptune’s moons are too faint for the 130 to pick up, and the planets themselves will look like nearly stellar dots.

Can you do astrophotography with Astro Fi 130?

The Astro-Fi 130’s mount is an alt-azimuth design, and while it is plenty accurate and stable for visual astronomy, it is not really capable of supporting a heavy camera for astrophotography, nor tracking in an equatorial configuration to enable long exposures. You could do planetary imaging with the Astro-Fi 130, but to achieve the optimal focal length and image scale, you’ll need either a 5x Barlow or to stack multiple 3x/2x ones.

Alternatives and Competition

The Astro-Fi 130 is our favorite of the Celestron Astro-Fi line. The Astro-Fi 102mm Maksutov lacks enough aperture or field of view to make it worthwhile, while the Astro-Fi 90mm refractor is a bit much for its mount to handle and also lacks a decent amount of aperture. Celestron also sells 5” Maksutov- and Schmidt-Cassegrains and a 6” Schmidt-Cassegrain atop the Astro-Fi mount, but these are not available in the US at the time of writing. The Astro-Fi 127 and Astro-Fi 5 have no real advantages over the 130, while the Astro-Fi 6 is simply unsteady due to the higher weight of the 6” Schmidt-Cassegrain optical tube.

The Celestron Astro Fi 130 is a decent enough telescope, but for the price you aren’t getting a lot of aperture. It’s one of the better deals on a computerized telescope out there, but an 8” or larger Dobsonian is simply no match for the little 130mm f/5 optical tube, offering significantly brighter and sharper views than the Astro Fi 130 can possibly hope to.

Under £600

  • The StellaLyra 8”/Zhumell Z8/Orion SkyLine 8 offers 2.5 times the light gathering ability of the Astro Fi 130 and 60% more resolving power, transforming “faint fuzzy” deep-sky objects into recognized and detailed wonders, revealing the disks of the faint ice giant planets, and showing details on Mars and Jupiter that a mere 5.1” of aperture just can’t. The dual-speed focuser, included eyepieces, and features like the built-in cooling fan and adjustable bearings for balance are also excellent value for the price.
  • The Explore Scientific 10” Hybrid Dobsonian provides 4x the light gathering ability and double the resolving power of the Astro Fi 130 and collapses into a compact cubic package that is actually almost as easy to store and transport as the Astro Fi telescope package. The included accessories aren’t very good, however, and assembly takes more steps than a solid-tubed scope (though it’s still less complicated than setting up the Astro Fi 130 for a night of observing).
  • The Orion SkyQuest XT8 is a bit more of a budget pick, but provides similarly bright and sharp views to the AD8 and its siblings, albeit stripped of almost all features and accessories and only slightly less expensive. 
  • The Sky-Watcher Virtuoso GTi 150P has more aperture than the Astro Fi 130 and a fully motorized mount with GoTo, controlled via your smartphone or tablet just like the Astro Fi. However, the extra inch of aperture provides significantly brighter views with more sharpness/resolving power, and the scope can be pushed around the sky manually withotut affecting its alignment on the stars, something the Astro Fi mount cannot do. The collapsible tube and tabletop Dobsonian mount make it quick to set up and easy to transport almost anywhere. The manual Heritage 150P is identical to the GTi 150P in features, performance, and accessories apart from having the electronics stripped away, leaving you with an all-manual tabletop Dobsonian telescope.


  • The StellaLyra 10”/Zhumell Z10/Orion SkyLine 10 features 4x the light gathering power and double the sharpness and resolution of the Astro Fi 130 on account of having about twice as much aperture, and the Dobsonian mount is incredibly easy to set up and use. A solid-tube 10” Dobsonian is hardly any heavier or bigger in volume than an 8” and is thus equally easy to set up and transport, but the views are significantly better. As with the AD8 and its siblings, this telescope package includes a plethora of high-quality features and accessories including a dual-speed 2” Crayford focuser, a 2” wide-angle 30mm SuperView eyepiece, a 9×50 right-angle, correct image finder scope, a laser collimator, and even a built-in cooling fan.
  • The Celestron StarSense Explorer 8” Dobsonian is incredibly basic with its features and accessories, including just a single eyepiece, a single-speed 2” Crayford focuser, and a red dot finder. However, it features some computerized capability in the form of Celestron’s StarSense Explorer technology, which doesn’t move the telescope automatically for you nor track sky objects with motors, but does use your smartphone as a pointing aid for locating objects in the night sky. The compact and lightweight Dobsonian base along with carry handles on the tube make transport a breeze, too.
  • The Sky-Watcher 8” FlexTube Dobsonian features a collapsible tube to increase portability (though it hardly cuts down on weight) and pereforms similarly to many of the other 8” Dobsonians in our rankings, though there are no deluxe features – the eyepieces included are both 1.25”, the focuser is a single-speed, and the finder is a straight-through rather than a right-angle unit. As with any other scope of this size, it easily outperforms the little Astro Fi 130 thanks to its much larger aperture, yet arguably remains easier and quicker to set up and use thanks to the simplicity of the manual Dobsonian mount.

Aftermarket Accessory Recommendations

The Astro Fi 130 is a nice enough telescope that it’s worth budgeting some extra for accessories. For starters, while the provided pair of eyepieces is decent enough, you’ll certainly want multiple additional eyepieces for more magnification options. For medium power, a 16mm UWA (41x) is an immersive and sharp option, while a 15mm redline/goldline (43x) makes for a decent budget alternative. A 10mm UWA (65x), or a 9mm redline/goldline (72x), is sharper, provides a wider field of view, and is more comfortable to use than the Astro Fi 130’s stock 10mm ocular, while for higher magnification, a 4mm planetary eyepiece or 4mm UWA (163x) is a good pick. A Cheshire collimation tool is also a good item to have on hand to ensure accurate collimation for the sharpest possible views with the Astro Fi 130.

Another accessory we would advocate for is a rechargeable battery or power supply capable of running the Astro Fi mount for an extended period, such as a generic 12V lithium power bank or the Celestron PowerTank Lithium. Frequent use of the telescope is likely to consume a substantial number of AA batteries. A rechargeable battery solution addresses this concern while also removing the necessity to power the scope from your car or via an unwieldy extension cord, which can be rather inconvenient.

Lastly, a narrowband Ultra High Contrast (UHC)/OIII nebula filter can significantly enhance your observation experience of nebulae, like the Orion Nebula, when used with the Astro Fi 130 or almost any other telescope with adequate aperture. This specialist filter also streamlines the process of locating planetary nebulae by reducing the brightness of surrounding stars and darkening the background sky, and can bring out previously-invisible objects like the Veil Nebula if you are fortunate to possess reasonably dark skies as well.
