If you want to control your telescope via an iPhone or Android device, this is the one to price-check.
The AstroFi 102 in Short
The Celestron AstroFi 102 Wi-Fi Maksutov is for the mobile observer who needs a compact 102mm Maksutov-Cassegrain telescope with integrated Wi-Fi control for smartphone use.
Manual re-centering and complex alignment often prevent beginners from capturing clear images of celestial bodies. This frustration occurs when a telescope’s mount requires constant adjustment to keep a planet in view.
The Celestron AstroFi 102 Wi-Fi Maksutov resolves this by using a Single Fork Arm Computerized Altazimuth mount. Its integrated Wi-Fi control allows you to operate the telescope via the Celestron Sky Portal app on an iPhone, iPad, or Android device.

The Short Answer on the AstroFi 102
Best for: you need a compact, computerized telescope for mobile viewing and remote operation via a smartphone or tablet.
The AstroFi 102 is a practical choice for mobile users at the $339.99 price point.
- Pro: Integrated WiFi control allows for remote operation via the Celestron Sky Portal app on Android and iOS devices.
- Pro: The 102mm Maksutov-Cassegrain design provides high-contrast optics in a portable form factor.
- Pro: It includes a mirror star diagonal and two Kellner eyepieces to get started immediately.
- Con: The 102mm aperture is below the 130mm threshold required to resolve the moons of Jupiter and rings of Saturn in detail.
- Con: The accessory tray is limited to holding two 1.25 eyepieces, restricting your ability to swap multiple lenses during a session.
Don’t buy this if: you require an aperture of 130mm or larger to achieve high-resolution planetary imaging.
Price assessment: The $339.99 price is fair for a computerized Maksutov-Cassegrain that includes a dedicated accessory tray and WiFi support.
RecommendedOptics score: 6.5/10 (data-driven – see “How we picked” above)

Before You Buy: AstroFi 102 Checklist
The first thing to check is your local Wi-Fi signal strength, as the AstroFi 102 relies on a stable connection to the Celestron Sky Portal app for its smart features.
- ☐ Confirm your smartphone is compatible with the Celestron Sky Portal app—iOS, iPad, and Android devices are supported.
- ☐ Measure your available storage for the app—the AstroFi 102 uses the Sky Portal app for Wi-Fi control.
- ☐ Verify your mounting space—the telescope uses a Single Fork Arm Computerized Altazimuth mount.
- ☐ Check that you have space for the included accessories—the accessory tray holds 2 x 1.25 eyepieces and a rubber-lined area for a smartphone.
- ☐ Confirm your support needs—this model includes a 2-Year US Warranty and US-based support.
You should not buy this product if you require a large aperture for high-magnification planetary detail, as the 102mm Maksutov-Cassegrain design prioritizes portability over the 130mm aperture threshold needed to resolve the moons of Jupiter clearly.
For a larger aperture with similar technology, examine the Astro Fi 130 spec breakdown to see the differences.
What the Numbers Mean in Use
Wi-Fi Connectivity and App Integration
The Celestron AstroFi 102 features integrated Wi-Fi control via the Celestron Sky Portal app. This allows you to control the telescope and view the feed directly from an iPhone, iPad, or Android device. By using the app, you can navigate celestial objects without needing to manually adjust the mount for every movement.
The AstroFi 102 includes an accessory tray with a rubber-lined area specifically for a smart phone or small tablet. This setup ensures your device remains stable while you use the app to guide your observations. Because the app handles the positioning, you can focus on identifying targets rather than mastering complex manual controls.
Compact Maksutov-Cassegrain Optics
The AstroFi 102 uses a 102mm Maksutov-Cassegrain telescope design with fully coated glass optics. A 102mm aperture is the threshold where you can resolve the moons of Jupiter and the rings of Saturn. While it is smaller than the 8-inch to 10-inch Dobsonian standard used for high-performance visual astronomy, this compact design provides high contrast for planetary viewing.
A common mistake is assuming a smaller aperture means lower detail; however, the Maksutov-Cassegrain format provides a long focal length in a short tube. The AstroFi 102 provides enough magnification to see Saturn’s rings clearly. If you require more fine detail on planets than this 102mm aperture provides, you would need to move to a larger 8-inch mirror system.
Computerized Altazimuth Tracking
The AstroFi 102 uses a Single Fork Arm Computerized Altazimuth mount to track objects in the sky. Because this mount type moves on two axes (altitude and azimuth), it is simpler to set up than an equatorial mount. You can command the telescope to move to specific coordinates, which simplifies the process of finding deep-sky objects.
The Single Fork Arm design is more compact than heavy-duty mounts, which can lead to more shaking during high-magnification viewing. To steady the view for photography or steady observation, you should ensure the tripod is on a firm surface. If you find the mount shakes too much for your specific targets, you would need a heavier, multi-arm mount to provide a more stable platform.
How the AstroFi 102 Compares to Alternatives
The AstroFi 102 provides a distinct advantage over the other reflector telescopes we evaluated by offering integrated WiFi control via the Celestron Sky Portal app.
- The AstroFi 102 costs $10 more than the 150EQ Equatorial Reflector Telescope.
- The AstroFi 102 costs $10 more than the Orion Observer 134mm Equatorial Reflector Telescope.
- The 130EQ Newtonian Reflector Telescope features a 130mm aperture, which is larger than the 102mm aperture on the AstroFi 102.
- The 150EQ Reflector Telescope has a 5.0 rating, while the AstroFi 102 has a 3.8 rating.
- The AstroFi 102 costs $10 less than the 150EQ Reflector Telescope.
- The AstroFi 102 costs $20 less than the 130EQ Newtonian Reflector Telescope.
The app functionality is a functional tool rather than a gimmick because it allows for remote control and navigation via iPhone, iPad, and Android devices. If you need to verify the specific software features, check the Celestron Sky Portal app compatibility list for the latest firmware updates.
If you require a larger aperture to resolve finer details on planets, choose the 130EQ Newtonian Reflector Telescope instead of the AstroFi 102.
Is the Price Right?
The Celestron AstroFi 102 sits at the $339.99 mark, which is $0 below the $340 average of the similar reflector telescope products we compared. At this price point, you receive a 102mm Maksutov-Cassegrain telescope with integrated WiFi control and a single fork arm computerized altazimuth mount. You are trading the larger aperture of an 8-inch to 10-inch Dobsonian—the industry standard for high-performance visual astronomy—for a more compact design that includes a star pointer finder scope and a mirror star diagonal.
You should choose the AstroFi 102 if you require a computerized mount with smartphone compatibility and want to avoid the bulk of a Newtonian reflector. While the included Kellner eyepieces are entry-level, the telescope provides a 2-year US warranty and US-based support. If you plan to eventually replace the included accessories with high-quality glass, you should factor in those additional costs before purchasing, as the current price covers the basic optical and mounting package.
Where this sits in the buyer data: Among the 25 products screened for this category, this one’s 3.8 rating places it #17, on 213 ratings – above the 37-rating median of that group, so the average rests on more feedback than most of its comparables. On price it undercuts 11 of them.
