Do we have a new challenger in the harmonic drive arena ? Enter the $500 Teseek 14 mount! Strain wave gear mounts also called harmonic drive mounts, have become the hot ticket in astrophotography over the last few years. Their light weight, compact design, and counterweight-free operation have made them the darlings of portable astrophotography rigs. Typically, though, they come at a steep price. ZWO’s AM3 and AM3N, for example, will set you back about $1,500–$1,600.
But what if you could pick up something with nearly identical specs for just $500? That’s exactly what Cuiv, The Lazy Geek, stumbled upon while browsing AliExpress. And in true Cuiv fashion, he decided to test it - warts and all.
The mount tips the scale at just 2.3 kilograms (about 5lbs), making it one of the lightest equatorial mounts on the market. Out of the box, it comes with a wedge, a USB-C cable, and even a somewhat sketchy counterweight shaft (which most will probably ignore). The attachment points for the dovetail saddle aren’t the most confidence-inspiring, but once tightened, they hold firm.
Two versions are available: one with 3D-printed covers (like Cuiv tested) and another with aluminum covers for about $70–$80 more. Even with the budget version, the mount feels workable - especially for a setup designed to travel light.
Power comes from a simple 12V DC input or a portable battery, perfect for field use. A USB-C port handles control, though Wi-Fi and Bluetooth connectivity are also baked in. The “on/off” button is misleading - it doesn’t actually power the mount, but rather switches on a green polar alignment laser. Useful in some countries, questionable in others.
The mount runs OnStep firmware, a common choice among smaller Chinese manufacturers. This means compatibility with ASIAIR, NINA, and standard planetarium apps. It also means you’ll need to handle meridian flips manually - no imaging straight through.
On paper, the mount supports payloads up to 10 kilograms without counterweights. In practice, Cuiv found it best suited for small refractors and lightweight rigs - think Askar FRA400C, SVBony SV550, or even camera lenses.
Guiding performance landed around 1 arcsecond RMS over the night. Declination behaved well, but right ascension showed periodic error every 440 seconds, with ±159 arcsecond swings. Guiding software struggled to keep up without aggressive tuning. Still, for wide-field imaging, star shapes came out sharp and usable.
Altitude adjustments were smooth and simple, but azimuth controls proved frustrating. In the dark, the locking screws are awkward and prone to causing wobble if not set firmly. Compared to the Sky-Watcher Star Adventurer GTi or ZWO’s wedge, this is a definite weak point. Expect 3–5 minutes to achieve a solid polar alignment - not terrible, but not great either.
What this mount lacks in refinement, it makes up for in portability. A complete astrophotography rig - with telescope, camera, tripod, and battery - came in around 8 kilograms in Cuiv’s test. Silent slewing, USB-C power, and backpack-ready size make it a dream for grab-and-go astrophotography.
At $500, this is a no-brainer entry point into strain wave gear mounts. At $1,000, you’d be better off saving for the ZWO AM3 or ProxySky alternatives.
Cuiv summed it up best: this mount isn’t perfect, but at $500, it’s a steal. The guiding quirks, cheap wedge, and odd design choices don’t overshadow the value. For travelers, beginners, or anyone who wants to dip into harmonic drive mounts without breaking the bank, it’s worth a look.
If you’re considering one, just don’t wait until the price doubles.
