ZWO ASI120MM Mini Mono Guide Camera – Used

Used – Very Good Condition. A pre-owned ZWO ASI120MM Mini monochrome guide camera, the long-standing standard for autoguiding. It shows only light cosmetic wear from normal use and is otherwise in very good shape.

What's Included

• ZWO ASI120MM Mini monochrome camera body
• USB cable

No other accessories are included — no ST4 guide cable, 1.25" nosepiece, CS-C adapter, or original box.

Condition Notes

• Light cosmetic wear consistent with normal observatory and field use; no functional issues noted.
• Sold as camera body plus USB cable only. If your guide scope requires a 1.25" nosepiece, you will need to source one separately.

About the ASI120MM Mini

The ASI120MM Mini pairs a 1/3" AR0130CS monochrome sensor (4.8 x 3.6 mm, 1280 x 960 pixels) with an ultra-compact, lightweight body designed to drop straight into a guide scope or off-axis guider. Monochrome sensitivity means it pulls in guide stars a colour camera would miss, and its small footprint and low power draw make it a natural fit for ASIAIR and other compact imaging rigs. It remains one of the most widely supported guide cameras in astrophotography — PHD2, N.I.N.A., ASIAIR, and SharpCap all recognize it out of the box. An easy way to add reliable autoguiding to an imaging setup for well under the price of a new unit.
