ASI120MM Mini (mono)Guide Camera The ASI120MM Mini camera integrates the AR0130CS 1/3″ sensor (4.8 mm x 3.6 mm). It is a new model in the “mini”-series of cameras from ZWO. This camera has 1280 x 960 pixels with a pixel size of 3.75 μm x 3.75 μm. It provides 12-bit ADC and the QE peak is almost 80%. The ASI120 mini-camera offers you very good performance for planetary imaging as well as for guiding. Low read noise, high dynamic range, AR protective window and much more are just some of the key characteristics that set it apart from the competition.

Guide Cameras and Guide Scopes Quick Overview • Lightweight and compact ZWO f/4 Mini Guide Scope with 30mm aperture and focal length of 120mm • Works with all ZWO cameras including the ASI120-series and ‘Mini-series’ autoguiding cameras • Ideal for autoguiding during astrophotography with telescopes of <1200mm effective focal length • Includes mounting bracket and rings • Threaded adjustable objective cell enables 0- 20mm of back focus Product Details The ZWO Mini Guide Scope weighs in at just over half a pound (240g), but it’s a powerful tool when matched with a sensitive ZWO camera for autoguiding during astrophotography. With a multi- coated 30mm cemented lens, this f/4 scope has a focal length of 120mm, ideal for autoguiding a main scope with an effective focal ratio of about 1200mm or less. This guide scope focuses with a threaded front objective cell that allows an adjustable back focus of 0-20mm. You can directly thread a ZWO camera such as the ASI120-series onto the male M42x0.75 threads on the scope. Or you can directly insert a camera with a 1.25" nosepiece or a smaller ZWO autoguiding camera such as the ASI290MM-Mini or ASI120MM-Mini and lock it down with the two locking screws. This little scope comes with guide rings and a Vixen/Synta style dovetail, which makes it easy to mount on nearly any telescope. The dovetail base also includes a ¼-20 screw hole for mounting on a photo tripod if you wish to use the scope as a camera lens or for visual viewing with an eyepiece. The entire scope, without the camera, is just 4.8” long (about 123mm). A camera is not included with this guide telescope. Specifications: • Lens Diameter: 30 mm • Focal Length: 120 mm • Weight (include guider ring and dovetail): 240g / 8.47oz • Back Focus: adjustable,（0~20 mm） • Focuser Type: front part focuser • Tube travel: 20 mm • Dovetail includes 1/4″ screw hole.
