The Widest Field of View Guiding or Off-Axis Guide Camera of the ZWO Mini Range

The ZWO ASI 174MM Mini Astronomy Camera is a member of ZWO's Mini Camera range, built specificially for large field-of-view guiding. In fact, the ASI174MM Mini has a field of view 4x larger than the entry-level ASI120MMMini! This makes the ZWO ASI174MM Mini USB2.0 Mono Guide Camera the best option from ZWO for long exposure guiding using a telescope with a long focal length such as a Schmidt Cassegrain or RASA and if using a full-frame camera. 

Compared to the ZWO ASI174MM, the ZWO ASI174MM Mini is 58% size of the standard ZWO ASI174 range and 42% of the weight! It also features a integrated 1.25" nosepiece, which enables the ZWO ASI174MM Mini to focus at the same position as an eyepiece.
