Excellent Choice for Affordable Planetary and Deep Sky Imaging

The NEW USB3.0 version of ZWO ASI120MC-S is an excellent choice for those starting in Astro photography and looking for an affordable planetary or deep sky one-shot colour camera. It is perfect for beginners who want to step up from modified webcams or cheaper planetary imagers without breaking the bank.

Enhanced USB3.0 Connectivity

This NEW version comes with USB3.0 connection, enabling higher frame rates and better results in planetary imaging when used with newer laptops.

Auto guider Port for Versatility

The camera is equipped with an AUTOGUIDER PORT, allowing you to use it for both imaging and guiding, making it a versatile tool for Astro photography.

Better Results and Great Value for Money

The ZWO ASI120MC-S camera offers better results compared to beginner cameras like TSSI or Scopium cam, providing improved performance at an affordable price. While there are more expensive options like Moravian Instruments cameras available, ZWO cameras are considered to offer the best value for money on the market.
