The ZWO ASI 120MM Mini is the most popular guiding camera on the market with the best price/performance ratio.
The ZWO ASI 120MM Mini contains the AR0130CS CMOS monochrome sensor which has a diagonal of 6.00 mm and a resolution of 1.22 megapixels.
The sensor has a high QE that reaches almost 80% at 540 Nm.
The ASI 120MM Mini uses a USB 2.0 type C port and it is also equipped with a ST4 port as guiding alternative.
Compared to the classic ASI 120MM camera, the ASI 120MM Mini is lighter and has a shorter back focus that makes it ideal for off-axis guiders or finderscopes.

Have a ASI120mm for past few years for guiding. Never misses a beat. Added a second camera for another scope setup for the EQ8 to save camera swapping. Great little camera. love the more compact size and USB3 from the original 120mm. Highly recommend. As usual - prompt great service from Adriano and the team !
After borrowing a loan scope and mount, I purchased this camera, small guide scope and ASiair plus to add to my Star Adventurer mount and EOS 550D camera. This setup now is so much easier to use and allows me to take much longer exposures which reduces processing time and storage requirements.
Works great and so happy with this purchase.
When combined with the WILLIAM OPTICS 50mm RED GUIDE SCOPE, you end up with a fantastic guide scope. Have been using it for auto-guiding with fantastic results
Purchased for auto guiding, was surprised by its performance, small in size but produces great results.
Great little camera, does what it's supposed to.
